Calorimetric studies of the glass transition phenomenon in glassy Se 75Te15-xCd10Inx alloys using the non-isothermal DSC technique

Abstract

Glass transition kinetics was studied in a glassy Se75Te 15-xCd10Inx (x = 0, 5, 10 and 15) system. Differential scanning calorimetric (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) was studied using different non-isothermal methods. The activation energy of glass transition (Eg) was evaluated using Kissinger's relation and the theory of Moynihan. The composition dependence of Tg and E g is also discussed. © 2010 The Royal Swedish Academy of Sciences.
