Abstract: Different methods have been used by various workers to determine the activation energy of thermal crystallization (Ec) in chalcogenide glasses using non-isothermal DSC data. In the present work, the crystallization kinetics of two important binary alloys Se80Te20 and Se80In20 is studied, using non-isothermal DSC data. DSC thermograms of these alloys have been taken at five different heating rates. The values of activation energy of crystallization (Ec) have been determined by four different methods, i.e., Kissinger’s relation, Matusita and Sakka theory, Augis and Bennett’s approximation and Ozawa’s equation. The results obtained have been compared with each other to see the effect of using different methods in the determination of Ec. The composition dependence of Ec has also been discussed.
