Results of non-isothermal crystallization studies performed at various heating rates on nine glass compositions of the As-Sb-se system with composition represented by (As,Sb)//4//0Se//6//0 and As//xSb//1//5Se//8//5// minus //x are presented. Composition dependence of T//p, T//c - T//g, DELTA H//c and E//g are discussed. The crystallization data are examined using an analysis developed for non-isothermal crystallization. Bulk nucleation with two and three dimensional growth are indicated respectively for the As//xSb//1//5Se//8//5//31 //x and (As, Sb)//4//0Se//6//0 glasses. The activation energy for crystal growth obtained by these experiments and analysis agree with the electron microscopy data.
