Kinetics Study of (Se80Te20)100–xCdx Glassy Alloy by Differential Thermal Analysis Using Non-Isothermal Technique

The kinetics of crystallization in (Se80Te20)100 – xCdx (x = 0, 2, 4 and 6) alloys at different heating rates have been studied by Differential Thermal Analysis in non-isothermal condition. A comparison of various quantitative methods to assess the level of stability of the glassy material in the above mentioned system is presented. All these methods are based on the characteristics temperature obtained by heating of the samples, such as glass transition temperature (Tg), temperature of crystallization (Tc), and the melting temperature (Tm). From the dependence of glass transition temperature on heating rate, the activation energy (Eg) has been calculated on the basis of the Kissinger and Moynihan models.
