Abstract: Alloys of Te-Bi-Se glass system, obtained by rapid quenching technique, have been characterized by calorimetric measurements and differential thermal analysis for different heating rates. Variation in two important parameters, namely, glass transition temperature Tg and glass forming ability Kg1 have been studied with variation in Bi content at various heating rates. By analyzing the results, it has been seen that, with the increase in Bi content the glass forming ability Kg1decreases. However, with the increase in heating rates, the glass transition temperature Tg is found to increase. This analysis helps in finding the suit ability or an alloy to be used in phase transition optical memories/switches. The results have been analyzed using Kissinger's equation for non-isothermal crystallization of materials.
