Durehglühbarkeit ausgenutzt wird, d. h. auf die Herstellung von verschiedenartig gestalteten Körpern und Behältern aus solchen Massen, wie sie zur Ausführung von 8cllUwlzungen und anderen Prozessen, die bei hoher Temperatur ausgeführt werden müssen, notwendig sind, und weiche man bisher entweder nur aus Metall oder gegebenenfalls auch aus Quarz und Quarzglas erzeugte.
Die Durchführung des Verfahrens zur Schaffung des geschilderten Metallersatzes kann in verschiedener Weise erfolgen, regelmässig kommt aber eine metallhaltige Flüssigkeit zur An Wendung, die auf irgend welchem Wege geschaffen werden kann ; es kann z. B. eine Metallsalzlösung sein oder eine Lösung oder Aufschwemmung von Metalloxydverbindungen oder auch ein Metallpräparat in kolloidaler Form. Die zur Herstellung der verschiedenen Gegenstände verwendete keramische Masse muss porös sein, d. h. sie wird zweckmässig aus Ton, Biskuitporzellan oder dgl. bestehen.
Aus dieser Masse werden dann die dem vorliegenden Verwendungszweck angepassten Körper oder Gegenstände, wie Schalen, Muffeln, Tiegel, Kolben, Röhren, Becher, Schmelzplättchen usw., und ebenso Geräte, wie Löfel, Spachteln, Schaber, Pinsel usw., hergestellt. Damit nun diese Körper oder GEgenstände die gewünschte Hitzebeständigkeit und auch die leichte Durchglühbarkeit besitzen, welche den Edelmetallgegenständen eigen ist, wird die keramische Masse mit der metallhaltigen Flüssigkeit angerührt, gut durchgearbeitet, damit sie sich gleich- mässig sättigt, dann zu dem entsprechenden Gegenstand geformt, getrocknet und gebrannt.
Bei diesem Brennen verflüchtigen sich dann die übrigen Bestandteile der Metallverbindungen und es verbleibt das Metall allein in der denkbar feinsten und durchaus gleichmässigen Verteilung in
EMI2.2
An Stelle des beschriebenen Herstellungsverfahrens kann man aber auch die jeweils gewünschten Körper oder Gegenstände aus keramischer Masse formen und diese Körper in un-
EMI2.3
mit dieser sättigen, worauf dann nochmals gebrannt oder ausgeglüht wird. was das gifichf Ergebnis hat, wie oben beschrieben.
Edle Metalle, wie Platin, Gold, Silber usw., werden bei der beschriebenen Behandling olme weiters in ihre metallische Form zurückgeführt, in welcher sie die Körper und Gegenstände gleichmässig durchsetzen. Unedle Metalle bleiben dagegen zunächst in Form ihrer Oxyde zuruck. können aber in einer für die beabsichtigten Zwecke hinreichend tiefen Schicht in ihre Metaliform durch Anwendung bekannter chemischer Reaktionen zurückgeführt werden, was z. B. in folgender Weise geschehen kann. Leicht reduzierbare Metalloxyde bzw. unorganische Metallverbindungen

EMI2.1
Durehannbarkeit is exploited, d. H. on the production of differently shaped bodies and containers from such masses as are necessary for the execution of 8cllUwalzungen and other processes that have to be carried out at high temperature, and which up to now have been made either only from metal or possibly also from quartz and quartz glass .
The process for creating the metal substitute described can be carried out in various ways, but regularly a metal-containing liquid is used which can be created in any way; it can e.g. B. be a metal salt solution or a solution or suspension of metal oxide compounds or a metal preparation in colloidal form. The ceramic mass used to make the various objects must be porous; H. it will expediently consist of clay, biscuit porcelain or the like.
The bodies or objects adapted to the intended use, such as bowls, muffles, crucibles, flasks, tubes, beakers, melting plates, etc., and also devices such as spoons, spatulas, scrapers, brushes, etc., are then made from this mass. So that these bodies or objects have the desired heat resistance and also the easy glowing properties that are inherent in precious metal objects, the ceramic mass is mixed with the metal-containing liquid, worked through so that it is evenly saturated, then shaped into the corresponding object, dried and burned.
During this firing, the remaining constituents of the metal compounds then evaporate and the metal remains in the finest and most even distribution possible
EMI2.2
Instead of the manufacturing process described, however, the desired bodies or objects can also be formed from ceramic mass and these bodies in un-
EMI2.3
saturate with this, which is then again fired or annealed. what the gifichf result has as described above.
Noble metals such as platinum, gold, silver, etc., are also returned to their metallic form in the treatment olme described, in which they evenly permeate the bodies and objects. In contrast, base metals initially remain in the form of their oxides. but can be returned in a sufficiently deep layer for the intended purposes in their metal form by using known chemical reactions, which z. B. can be done in the following way. Easily reducible metal oxides or inorganic metal compounds
