Abstract

Alkali silicate glasses are described which, in view of their good chemical stability and their optical properties and processing properties, are particularly suitable as a coating or veneering material for ceramic dental frameworks and hence for the production of all-ceramic dental restorations such as crowns or bridges. The alkali silicate glasses each contain the following components:
Component Wt. %
SiO2 55.0 to 71.0 Al2O3 5.0 to 16.0 B2O3 0.2 to 10.0 K2O 4.5 to 10.0 Na2O 3.0 to 14.0 A preferred form of these glasses contain at least one of the following components:
Component Wt.%
CaO 0 to 3.0 F 0 to 3.0 P2O5 0 to 0.6 Li2O 0 to 4.0 BaO 0 to 5.0 ZnO 0 to 4.0 TiO2+Zro2 0.2 to 5.0 CeO2 0 to 2.0
