Abstract

Results of thermal analysis performed at different heating rates on eight glasses of the As-Sb-Se system, with compositions represented by (As, Sb)//4//0Se//6//0 and As//xSb//1//5Se//8//5// minus //x are reported and discussed. The values of the glass transition temperature (T//g), the crystallization temperature (T//c) and the peak temperature of crystallization (T//p) are found to be independent of particle size. From the heating rate dependence of T//g and T//p, values of the activation energy for glass transition (E//t) and the activation energy for crystallization (E//c) are evaluated and their composition dependence discussed. The crystallization data are examined in terms of recent analyses developed for non-isothermal crystallization studies to arrive at E//c and details of the crystallization mechanism.
