Abstract

We have investigated the isothermal and non-isothermal crystallization kinetics in molecular glasses in the system Ag2O-SeO2-MoO3 with different modifier (Ag2O) contents. We have observed a change from two-dimensional to three-dimensional crystallization with the increase of the modifier content. We have shown that John-Mehl-Avrami and Sestak-Berggren models give the best description of the isothermal and non-isothermal crystallization kinetics respectively for the glass-crystal transformation.
