Definitions

These wires are designated under the name of son of "glass E”, whose archetype is described in US-A-2,334,961 and US-A-2,571,074, and which have a composition essentially based on silica, alumina, lime and boric anhydride.
the latter present at levels ranging from 5 to 13% in glass compositions known as “glass E”, is added to replace the silica in order to reduce the liquidus temperature of the formed glass and to facilitate its melting.
It is called “liquidus temperature”, denoted “T
T liquidus temperature
the liquidus temperature thus gives the lower limit at which it is possible to fiber.
the forming margin is defined as the difference between the temperature at which the viscosity of the glass is 1000 Poises (100 Pa ⁇ s), the temperature at which the glass is generally fiber, and the liquidus temperature.
These oxides further decrease the coefficient of thermal expansion of the glass, which has the effect of reducing the overall thermal expansion coefficient of the composite material, and therefore of increasing its dimensional stability.
Advantageous properties in terms of fiberization facility are also attributable to these two oxides, in particular related to an increase in the forming margin and a decrease in the crystallization rate at liquidus temperature.
the sum of the contents of these elements, denoted BaO + SrO is preferably greater than or equal to 0.8%, or even 1% and / or less than or equal to 2%, even 1, 5%.
the composition of the yarns according to the invention may comprise both these oxides, or, preferably, only one of them. When only one oxide is present, its content is preferably greater than or equal to 0.5%, even 0.8% and / or less than or equal to 1.5% or even 1.2%.
the content of manganese oxide is less than 1%, and preferably less than 0.3%. Since this oxide is capable of giving the glass a very intense purple coloration, the MnO content is preferably maintained below 0.1%, or even 0.05% and even 0.01%. Fluorine may be added in small amounts to enhance melting of the glass, or be present in the impurity state. It has been discovered, however, that small amounts of fluorine very clearly affect the temperature resistance of the glasses according to the invention. The fluorine content is therefore advantageously maintained below 0.5%, and especially less than 0.1%. Iron oxide is an unavoidable impurity of the glasses according to the invention because of its presence in several raw materials, and its content is generally less than 0.5%.
