A study of kinetics of phase transformation of Ge10Se75Sb15 chalcogenide glass
Source abstract
Abstract
Abstract Kinetics of phase transformation of Ge10Se75Sb15 chalcogenide glass, prepared by melt quenching technique, has been studied by differential scanning calorimetry (DSC) at different heating rates 5, 10, 15 and 20 K/min under non-isothermal condition. Dependence of glass transition temperature on heating rate has been studied by Lasocka empirical relation. The crystallization parameters such as activation energy of crystallization, Avrami index (n), dimensionality of growth (m) and frequency factor have been evaluated using Kissinger, Augis-Bennett, Ozawa and Matusita-Sakka model. Average value of n comes out as 1.73, which indicates one dimensional growth. Further an effort has also been made to study thermal stability using various parameters.
