Description

The subject of the invention is glass mass for the production of sensitive photochromic glasses which darken under the influence of irradiation with actinic radiation and revert to their normal colorless form after cessation of exposure. The closest prior art is disclosed in British Patent Specification No. 1,428. 880, where the following composition is claimed for the photochromic glass in percent by weight SiO2, 12.1-13.9; P2O5 - 30.4-33.9; Al203, 22.5-25.7; Zr02 - 1.0 - 2.6; NazO - 3.0-7.5; KzO - 5.3-10.5; CaO - 3.1-5.0; BaO - 3.1-7.0; SrO - 0-0.5; PbO - 0.4-2.5; TiO 2 0.1-0.6; La2O3 - 0.05-2.0; Ag20 - 0.05-1.0; CuO - 0-0.1; Cl and / or Br - 0.20 to 10.0. An analysis of the results presented in the aforementioned British Patent Specification shows that the glasses according to this invention meet the requirements for photochromic glasses to a very small extent due to the fact that they occur in problems of devitrification to a greater or lesser degree, poor regeneration capacity after irradiation (deadness), or due to too little transparency. The glass structures according to the above-mentioned British patent specification are characterized by a high halogen content, which can be considered responsible for too little transparency. This content is found to be 0.2-10.0% with a preferred upper limit being set at 6.0%. British Patent No. 1,367,903 describes and claims a series of photochromic glasses containing at least 17 wt. P2O5 as the main vitreous component and silver halide crystals dispersed throughout the mass, the total silver content being 0.05%. Particular glasses mentioned in the abovementioned patent are aluminum-phosphor glasses, containing no more than 40 wt. % SiO2 and from 9 to 34 wt.% A12C3 as a further glass forming agent and at least 10 wt. R20 where R is K, Na or Li. The above-mentioned glasses can also contain up to 19% by weight of B2O3, although most often they contain no more than 3 to 7% of B203. Glasses prepared in accordance with the claims of British Patent Specification No. 1,367,903 are used for the production of ophthalmic lenses, both anti-solar and corrective . Such aluminum-phosphor glasses, as well as photochromic boron-silicate glasses, which are also available on the market - as long as they exhibit the desired photochromic properties, react slowly to the initiation and interruption of exposure to actinic radiation. In other words, they have a low darkening capacity and a slow recovery rate to a colorless form. It is desirable, especially for ophthalmic reasons, to have lenses that are sensitive, ie that react quickly, and especially quickly fade. A high speed of fading (fade out) is desirable in order to speed up the perception with a sharp reduction in the brightness of the environment, as happens when a person with photochromic glasses enters a dark room. The intention of the present invention is to provide a number of types of photochromic glasses with more favorable properties, in particular glasses providing a better set of photochromic effects (expressed as excited optical density, or a change in light transmission under the influence of actinic radiation) and a faster response to the onset or removal of light exposure The compositions according to the invention are new and not obvious in relation to the state of the art. According to the present invention, the glass mass for the production of photochromic, aluminum-phosphor glass containing silver halide crystals dispersed in its entire mass contains in percent by weight: SiO 2 - 8.5-25.0; AlaO? - 13 to 36.0; P205 - 11.5-33.5; B203 - 7-28, RaO - 8.5-18, where R2O represents one or more oxides of Na2O, K20 and Li2O, with a maximum content of 5% by weight of Li2O, and in the case of B2Os content of 7–8% by weight, 16 % or more by weight of SiO2 and as photochromic components in an amount expressed as a percentage by weight of more than 100% of the total content of non-photochromatic components, contains silver, expressed as Ag, not less than 0.05% by weight and C1 + + Br 0.20 - 2.0% by weight The weight according to the invention in another embodiment comprises in percent by weight: SiO 2 - 8.5-25; Al2Oa - 36.01-36.5; P205 - 7.5-33.5; B203 - 7-28; RaO - 7-20.5, where R2O is as defined above, with R20 containing a maximum of 5% by weight of LiO2, and when the B2O3 content is 7-8% by weight, it contains 16% or more by weight of SiO2. and as photochromatic components in the amount expressed in percent by weight above 100% of the total content of non-photochromatic components, it contains silver, expressed as Ag20, not less than 0.05% by weight and Cl + Br - 0.20-2.0 % by weight. Yet another embodiment of the composition according to the invention comprises in percentages by weight: SiO 2 - 8.5-25; Al * Oj - 13-36.5; P2Os - 7.5-11.49; B203 - 7-28; R2O - 7-20.5, where R2O is as defined above, R20 containing a maximum of 5% by weight of Li2O, and when the content of B20 is 7-8% by weight, it contains 16% or more by weight. SiO2 and as photochromatic components in the amount expressed as a percentage by weight of more than 100% of the total content of non-photochromatic components contains silver, expressed as AgjO not more than 0.05% by weight and Cl + Br - 0.2-2.0 % by weight. A further embodiment of the weight of the present invention contains, in percent by weight, SiO 2, 8.5-25; A120 * - 13-36.5; PaOs - 7.5-33.5; B ^ - 7-28; R 2 O - 18.01-20.5, where R 2 is as defined above, where RaO contains a maximum of 5% by weight of Li 2 O, and when the B 2 O 5 content is 7 - 8% by weight, it contains 16 or more weight percent SiOj and as photochromatic components in the amount expressed in weight percent more than 100% of the total content of non-photochromatic components contains silver, expressed as Ag20 not less than 0.05% by weight and Cl + Br - 0.20-2.0% A further embodiment of the mass according to the invention contains, in percent by weight: SiO 2 - 8.5% 25; A1205 - 13-36.5; P205 - 7.5-33.5; B2Ot - 7-28; RaO - 7-8.49, where R20 is as defined above, where the RzO contains a maximum of 5% by weight of Li2O, and when the content of B2O3 is 7-8% by weight, it contains 16 or more% by weight of SiO2. and as photo-chromatic components in the amount expressed as a percentage by weight above 100% of the total content of non-photochromatic components contains silver, expressed as AgzO, not less than 0.05% by weight C1 + + Br - 0.20-2.0% Lenses with the above compositions have a good optical density induced by actinic radiation, darken quickly on exposure to light, and quickly become erroneous when exposure is interrupted. As a general rule, it should be assumed that the darkening times and fading are longer when the excited optical density is greater. In glasses made from pulp, according to the invention, the main component may be Al2Os, B203 or P205. Glass is best suited for ophthalmic purposes, in which the main component is Al2Os in an amount not lower than 22% by weight. and the P205 content does not exceed 25.5 wt.%. and the B203 content is not more than 24.5 wt.%. The composition of the glass mass selected within these limits provides a product with a high speed of response to exposure and cessation of irradiation while maintaining the remaining physical properties, which allow easy factory production and the manufacture of ophthalmic lenses. For example, the liquidus temperature and the viscosity of the molten glass can be adjusted simultaneously so as to be able to use the usual forming process and to obtain a glass with a hardness to the normal grinding and polishing treatment. The refractive index can be set to a value of 1.523, which is typical for ophthalmic products, and the glass can retain good chemical resistance and durability. In general, it is best to choose both A1203 and SiO2 equal to the upper content within the limits given above. when a high viscosity at the liquidus temperature is required, which must not be too high when the glass is used to form sheets. Other glass grades in the context of the present invention are preferably B 2 O 3. The weight of the glass thus comprises at least 25 wt. B * Oh, not more than 20 wt.%. Ak03 and no more than 20 wt.%. P205 In other grades of mass-made glasses according to the invention, the main component is P2O5 in an amount not less than 21.5% by weight; on the other hand, the Al 2 O 3 content did not exceed 26% by weight. and the B20 content is not more than 17.5% by weight. If, due to the use of a relatively large amount of B2O3 and a small amount of SiO2, the liquidus temperature is relatively low, it should be ascertained whether the prepared glass has a sufficient durability (determined by 10 15 20 25 30 35 40 45 50 551116TT 5 * e.g. as no traces of effect of acid or base solutions). The degree of durability depends, of course, on the intended use of the glass. Thus, glass with insufficient durability for ophthalmic purposes, but with good photochromic properties, can be used in instruments or for other purposes, as long as it is not exposed to an aggressive environment. close to the lower limit and is, for example, lower than 8%, a SiOi content of at least 16% must be maintained to ensure high photochromic sensitivity and durability of the ophthalmic product. If the glass contains less than 7% B2Oa, the P205 content must be kept below 17%. R20 may be K20 alone, or Na2O itself, or a mixture of two or three oxides from K20, NaaO and Li2O. When NajO is used alone, its content should not exceed 14% by weight. This avoids subsequent difficulties in forming the glass and reducing its durability. A very advantageous feature of ophthalmic glasses is their ability to be hardened by ion exchange, during which large metallic ions are replaced in the surface layer by small ions. Such replacement causes surface compression of the glass. The ion exchange is carried out by immersing the glass in a bath of molten salt. Typically, during a bath in the molten KNO, the sodium or lithium ions are exchanged for potassium, while in the molten NaNO3 the lithium ions are exchanged for sodium. Thus, if the glass is to be chemically cured by this method, it is most preferred that the dopant R3O consists of Na2O and LysO, or Li2O itself. However, it is preferable to use a mixture of alkali oxides which will always contain K2O, the content of both Na2O and LiO should be less than 5%. The depth at which the ion exchange takes place and the degree of surface pressure stress may be ¬ knows to regulate by changing the temperature of the melted salt in the bath. In general, the greater the depth of the exchange, the lower the surface pressure, and vice versa, a reasonable compromise must be established experimentally. As mentioned above, the silver content of the glass must not be lower than 0.05% by weight. based on Ag20, as it may be difficult to achieve sufficient darkening with lower Ag20 contents. Preferably, the Ag 2 content is at least 0.06%. The glass weight may also include from 1 to 21 wt.%. oxides of R'0, wherein the symbol R'0 represents at least one oxide from MgO, BaO, SrO and CaO. The individual oxides in the glass mass may be present in the following amounts: MgO 0-4% CaO 0-6.5% SrO 0-10% BaO 0-21% Glasses intended for ophthalmic purposes should have a suitable light refractive index. For the D line of sodium light it is 1.523. The reduction of the refractive index to this value is achieved by adding impurities such as TiO 2, ZrCb and PbO, or PbO alone, with the appropriate proportions of these components. These additives must be used with great care to avoid difficulties caused by too much of one or more of these ingredients. The amount of TiO 2 added should not exceed 6% by weight. to avoid the danger of crystallization and the undesirable discoloration of the glass mass. The best limiting content is 3 wt.%. The dopant of ZrO2 should not exceed 10 wt.%. if one wishes to avoid an undesirable increase in the liquidus temperature; the most suitable limit is 7 wt.% of Z1O2. PbO, on the other hand, may be introduced in amounts from 8% by weight. Small amounts of other dopants, such as HfOj (up to 3%) and ZnO (up to 6%), can also be introduced for the same purpose. Color additives can be added in a manner known per se to keep the permanent shade of the glass out of the variable photochromic tint. As is known, the photochromic effect produces the above-mentioned silver halide crystals. Smaller amounts of copper oxides assist in the photochromic effect. Larger amounts of these oxides additionally give a permanent color to the glass. The appropriate amounts of the photochromic components, namely silver (converted to Ag 2 O), cupric oxide and halides (Cl and Br), calculated as a percentage of the total mass of the glass, are as follows: AgjO from 0.06 to 0.60% CuO from 0.005 to 1.0% Cl + Br from 0.20 to 2.0% Cl 0-1.0% Br from 0.08 to 1.0% 35 in most cases the heat treatment of glass improves its photoprotection properties speech. The changes in viscosity caused by temperature changes determine the particularities of the heat treatment regime for each type of glass. In general, the temperature of the heat treatment process is between the decay temperature and the softening point of the glass. The heat treatment lasts from several hours at lower temperatures to several minutes at higher temperatures. However, at higher temperatures, deformation and thinning of the glass can occur, so it is best to treat it at a temperature 20 to 100 ° C above the stress point for 10 to 60 minutes. The glass can be heat treated immediately 50 days after forming, or the formed glass may be relaxed and cooled to room temperature prior to such treatment. The effect of the cooling rate after heat treatment on the photochromic properties of the final product is also sometimes observed. However, it is not possible to give general rules for the methods of cooling which must be established experimentally for the individual types of glass. The temperature-time regime of the heat treatment depends both on the concentration of the photochromic impurities 60 in the glass and on the desired photochromic properties of the final product. Typically, the higher the concentration of photochromism inducing components, the shorter the heat treatment time. It also happens that the photochromism may begin to manifest during the cooling of the molten mass or after the glass is reused. In general, excessively long heat treatment times should be avoided, as they may cause glass shading. The particular features of the invention are explained in more detail in the examples which are presented in Table I. The exact oxide composition of the glass masses according to the invention and the photochromic effect expressed by the excited optical density (ODd) and the time in seconds during which the total excited optical density drops to half of its original value (y OD FTJ. Both values were determined for normalized glass samples with a thickness of 2 mm, w conditions of standard simulated sunlight at air mass 2 (see Parry Moorv J. Franklin Inst. 230 (1940), pages 583-617). The excited optical density is the difference between the optical density of the glass in a completely obscured state and the density of in a completely colorless state Optical density is usually defined as Ii as log10 | 7 where Ii is the incident light intensity, it is the intensity of the transmitted light. The optical density excited is therefore a real measure of the photochromic effect, proportional to the number of photochromic excited silver atoms per unit of volume of the glass. The time required to fade from completely obscured to half the value of the induced optical density Iy OD FTJ is therefore an objective criterion for comparing the fade times of different glasses which have different light transmission values in a colorless state and in a fading state. This time can be compared with the half-error time mentioned in our earlier notification No. 1,367,903. Table I also gives the temperature (HT ° C) at which the type of glass was heat treated. In all cases - for easier comparison of results - the heat treatment lasted 20 minutes. Finally, Table I lists the values of the refractive index nD for most glasses. Table II shows the mass compositions of several types of photochromic glasses according to the invention and which can be chemically cured by the above-mentioned ion exchange. In the fourth and third lines from the bottom of Table II, the values of the compression in kg per cm are given. and the depth at which the ion exchange took place during a 16-hour bath in molten KNOj at 470 ° C., the photochromic characteristics of the hardened glasses are also given. In the case of glasses 174, 175 and 178, potassium ions were exchanged for sodium ions. In the glass 176 potassium ions are exchanged for sodium and lithium ions. In glasses 177 and 179, potassium ions are exchanged for lithium ions. It can be seen that in the process of chemical hardening, the photochromic properties are not changed, if one compares the "properties" of glass 174 with a very similar glass marked with the number 71 in Table I. 677 8 The glasses listed in the tables can be prepared as follows: The set of ingredients is fused in an oxidizing or inert atmosphere in the range of 1200 to 1000 ° C and, after cooling, it relaxes at a temperature between 450 and 650 ° C. The final heat treatment can then be carried out at a temperature of 20 to 100 ° C above the depressurization temperature in 10 to 60 minutes The temperature distribution for the heat treatment appropriate for a given and type of glass can be determined in an oven with a known temperature gradient. In some cases the glass samples must be supported in order not to break the temperature. The kits can be made from common glass raw materials such as carbon, meta or orthophosphates, nitrates and oxides. Silver and halides can be added in the form of silver salts, finely ground, and sodium or potassium halides. During melting, precautionary measures should be taken to reduce the volatilization of the components of the kit as this route can be lost up to 60% by weight. % halogen compounds and 30 wt. silver. These losses must be accounted for during the preparation of the batch. The glasses described above have a favorable set of photochromic effects, which manifests itself as excited optical density and the speed of response to the initiation or interruption of exposure to actinic radiation. Any excited optical density. may seem not very high to some glasses, but the response rate they display to actinic stimulus is particularly fast. The higher lenses can be used in ophthalmology as well as in other cases where it is a temporary protection against actinic radiation, eg solar radiation, and a return to normal light transmission after removal of actinic radiation. It can also be used in some cases for the glazing of buildings and vehicles. The photochromic effect of glass is associated with the formation of silver halide crystals, which are built into the spatial network of the glass and retain sensitivity to active radiation. The glass manufacturer is not only to select the composition of the set so that it can be melted and formed under the conditions at its disposal, but also must obtain a glass in which light-sensitive silver halide crystals are formed and the final product will have satisfactory properties. photo-chrome. Many hypotheses have been presented to explain the behavior of silver crystals embedded in the glass spatial network. British Patent No. 1,428,880 even states that under certain conditions and in some phosphorus glasses, silver halide is present in the amorphous form in the lattice of the glass. Due to the large number of components that can accommodate 60 in the glass mass, it is not It is possible to exhaustively investigate the effect of all petrmutations of these components, even of only selected groups of glass masses as defined in patent applications for simple glass masses without taking into account the influence of other additives. Problem-9 111677 does not become even more difficult when the admixing of other additives is to lead to the development of new physical properties, such as in the weight of the invention. We made a large number of glasses during the research from the groups of glass masses included in the patent claims. The examples taken in the above tables explain the invention in detail and indicate to what extent the amounts of the main glass-forming components, which are Al2Og, B203 and P3O5, in the individual compositions can be varied. These examples show how, despite the wide variety in the composition of the kits, it is possible to obtain glasses with a simultaneous and appropriate optical density and rapid darkening under the influence of irradiation and rapid fading after its break. As indicated above, it is recommended to use Al2Os as main component. Examples were given in which the ratio of B203 to PjOj contents was changed from B £ t concentrations greater than P * Os to BjOj concentrations equal to P2Os for the case of P1O5 concentrations higher than B2Oj concentrations. Examples are also given showing that suitable glasses can be made in which the main component is either B3O * or P2O1. In further cases, the possible changes in the proportions of these components are presented, e.g. when B2Oj Al ^ a P * 05 and BaOj P2O5 AfeOi P ^ s Al2Os B203 and P2O5 BtO, A120 |. The SiO2 content in the composition of the batch has little or no effect on the photochromic properties of the glass obtained. However, the ability to form the glass in further processing and the ability to cure by chemical methods depend on a sufficient SiO2 content. Thus, adjusting the SiO2 content in the batch to compensate for changes in the concentrations of the other main components (AljOj, P2O5, B ^ j) is a matter of having the appropriate experience of the technologist and knowledge of the effects on the properties of the glass obtained which may induce such changes. in Table I illustrate the acceptable limits within which the concentrations of the main components can be varied. Also presented are batch compositions in which the concentrations of the main components deviate from the stated limits in order to give a useful indication to the technologist / practitioner how to obtain the most suitable grade of glass. The above-mentioned examples of a large number of prepared and tested glasses make it possible to objectively evaluate the essence of the submitted invention, consisting in selecting the best composition of the batch in a wide range. The examples are given to better overall characterize the invention, and not to make its broad sense. They can also show that the composition of the glass mass can be subject to wide changes, with particular recommendation to use masses in which Al2Oi is the main component. In addition to the selection of the basic composition of the glass, it is equally important to select the appropriate amounts of photochromic additives: AgjO, CuO, Cl and Br. The possibility of changing the amounts of these additives with the same basic composition of the glass mass is also illustrated by the corresponding examples, e.g. masses No. 43 to 49. Still other changes in these compositions are shown for example mass No. 5, 7, 8, 9. , 57 and 58. It is easy to see that in general an increase in AgjO content is accompanied by an increase in the excited optical density. When selecting the basic composition of the glass, it is necessary to experimentally select both the type of photochromic admixtures and their concentration in order to obtain the desired value of the optical density in a given glass grade. As mentioned above, the final heat treatment can be applied. At times, it may be necessary to examine the effect of the duration of such treatment and the temperatures at which it is carried out. These parameters have a significant influence on the distribution of silver halide crystals in the spatial lattice of the glass and thus on the quality of the glass grade obtained. This test is best carried out with a rod-shaped glass sample in a furnace with a constant temperature gradient. The effect of changes in the heat treatment temperature and some changes in the amounts of photochromic additives while the basic composition of the glass is almost unchanged is illustrated by examples of weights 12, 50 to 56, 59 to 61 and 72 to 74. Additional corrections of the amount of photochromic additives may be needed. and changes in heat treatment conditions when it is necessary to change the basic composition of the composition to obtain a product with a suitable refractive index such as 1.523 <. The masses according to the invention make it possible to obtain optical glasses with a standard value of the refractive index of 1.523 ± 0.001 by making appropriate changes in the composition of the charges. The comparison of the masses quoted in Table I shows that the easiest way to prepare glasses with a coefficient equal to 1.523 ± 0.001 is when the main component of the set is Al ^ O. This type of mass has the best properties for the industrial production of glasses for ophthalmic purposes. However, it should be emphasized that the same refractive index has glass, made of a mass, the main component of which is B * Oa, as for example mass No. 173. Patent claims 1.
