Abstract

Sinterable lithium di:silicate glass ceramic contains (in wt.%): 57.0-80.0 SiO2; 0-5.0 Al2O3; 0.1-6.0 La2O3; 0-5.0 (esp. 0.1-5.0) Mg; 0-8.0 ZnO; 0-13.5 K2O; 11.0-19.0 Li2O; 0-11.0 P2O5; 0-8.0 colourants; and 0-6.0 additives. Al2O3+La2O3 = 0.1-7.0 wt.% and MgO+ZnO = 0.1-0.9 wt.%. The colourants comprise 0-5.0 wt.% glass-colouring oxides, and 0-5.0 wt.% coloured body. Also claimed is a process for forming a moulded dental product made of the glass ceramic.
