Description

Glass transition kinetics has been studied in a glassy Se80-xTe20Snx (0 ≤x ≤10) system. Differential scanning calorimetry (DSC) runs were taken at four different heating rates (5, 10, 15 and 20 K min-1) for this purpose. The heating rate dependence of the glass transition temperature (Tg) has been studied using different non-isothermal methods. The activation energy of glass transition (Eg) has been evaluated using Kissinger's relation and the theory of Moynihan. The composition dependence of Tg and Eg has also been discussed.
