Phase-Separation Phenomena in Glasses of Aluminosilicate Systems Containing Various Modifier Cations
This communication is a brief account of the results of a study of phase separation in aluminosilicate glasses containing oxides of Li, Na, Ca, Ba, Cd, Sn, and Zn. The need for such an investigation became obvious in studies of formation of glass-ceramics in these systems. A total of about 200 glass compositions were studied in the course of the investigation by electron microscopy and other methods both with and without addition of TiO2 as a catalyst of volume crystallization.
