Abstract

A systematic investigation of glass forming tendency and crystallization kinetics of the Ag_x-Sb_2(1–x)-Te_3(1–x) (x=0.16, 0.18, and 0.20) is reported. The alloy of the Ag-Sb-Te glass system, obtained by the rapid quenching technique, is characterized by calorimetric measurements and different thermal analysis for different heating rates. Variation in two important parameters, namely, glass transition temperature T_g and glass forming tendency K_gl, are studied with the variation of Ag content. By analyzing the results that occur with the increase in Ag content, we see that the glass-forming tendency K_gl also increases. However, with the increase in heating rates, the glass transition helps us to find the suitability of an alloy to be used in phase change optical memories/switches. The results are analyzed using Kissinger's equation for the nonisothermal crystallization of materials.
