摘要
Glass transition kinetics of Se82−xTe18Sbx (x = 0, 4, 8 and 12 at.%) glassy alloys has been studied using differential scanning calorimetry (DSC). DSC runs were taken at different heating rates (5, 10, 15 and 20 K/min) for each samples. Heating rate dependence of glass transition temperature (Tg) has been studied using Lasocka empirical relation. Activation energy of glass transition (Eg) has been determined using Kissinger and Moynihan’s relation. Effect of Sb concentration on glass transition temperature and activation energy has been studied. Thermal stability of Se82 − xTe18Sbx glassy alloys has also been investigated using Dietzal relation, Saad and Poulin relation, Hurby parameter (Hr) and Lie and Liu parameter (γ). Compositional dependence of parameters investigated for thermal stability has also been studied.
