Abstract

Differential Scanning Calorimetry (DSC) is performed at different heating rates under non-isothermal conditions to study the glass transition kinetics of glassy Se1 - xSbx (x = 0.02, 0.04, 0.06, 0.08 and 0.10) alloys. The activation energy of glass transition Et has been calculated using the two different non-isothermal methods. One of the two methods is based on the theory of glass transition kinetics and structural relaxation as developed by Moynihan and other workers, while the other relation is well-known Kissinger's relation. The results show that the values of Et determined from both the methods are in good agreement with one another. The variation of glass transition temperature Tg with heating rate and composition has also been studied and the results have been explained in terms of the glassy structure of Se-Sb system.
