Leucite crystallization from K2O – Al2O3 – SiO2 glass-forming melts

It is shown that the K2O – Al2O3– SiO2 system is promising for obtaining glass ceramic, containing leucite, for fabricating dental prostheses. Glass formation in this system and the crystallizability of glasses, including glasses modified with Li2O and Na2O, is studied. The effect of temperature and the time parameters on liquation and crystallization processes is studie
