On the glass transition phenomenon in Se-Te and Se-Ge based ternary chalcogenide glasses

Abstract

The present paper reviews the results of non-isothermal differential scanning calorimetry (DSC) measurements on some ternary glassy systems of Se-Te and Se-Ge chalcogenide alloys for evaluation of activation of glass transition. The activation energy of glass transition (Eg) is calculated using Kissinger's relation, which is basically derived for amorphous to crystalline phase transition. The results show that Eg values obtained from Kissinger's relation are in good agreement with the Eg values which are obtained using Moynihan's relation based on the concept of thermal relaxation. This proves the applicability of Kissinger's relation for determination of activation energy of glass transition. © 2009 Elsevier B.V. All rights reserved.
