- namentlichPATENTANSPRUCH :
Verfahren zur Herstellung halbleitender keramischer Glasuren, bei welchem den Glasurbildnern fein verteiltes Silber oder Silberverbindungen zugesetzt werden, wodurch die in der Glasur enthaltenen höheren Oxyde der Schwermetalle in niedere Oxyde reduziert und Spinelle gebildet werden, die Träger der Halbleitfähigkeit sind nach Patent Nr. 221412, dadurch gekennzeichnet, dass sich der Silbergehalt in der Glasur in den Grenzen von 0,001 bis 0, 10/0, bezogen auf den ausgeglühten Zustand, bewegt.
- in particular PATENT CLAIM:
Process for the production of semiconducting ceramic glazes, in which finely divided silver or silver compounds are added to the glaze formers, whereby the higher oxides of the heavy metals contained in the glaze are reduced to lower oxides and spinels are formed, the carriers of the semiconductivity are according to Patent No. 221412, thereby characterized in that the silver content in the glaze ranges from 0.001 to 0.110/0, based on the annealed state.
