Abstract We report the calorimetric study of amorphous Se{sub 30}Te{sub 70-x} Sn{sub x} alloys for x= 0, 1.5, 2.5, 4.5 in terms of kinetic parameters. The DSC curves recorded at four different heating rates are analyzed to determine the transition temperatures, activation energy, thermal stability, glass forming ability. The crystallization process has been investigated using Kissinger, Matusita, Augis and Bennett, and Gao and Wang models. Various kinetic parameters have been calculated for a better understanding of the growth mechanism. The glass transition temperatures T{sub g}, onset crystallization T{sub c}, peak crystallization T{sub p}, and melting temperature T{sub m} are found to increase with the increase in Sn content. The system under investigation is found to be thermally stable for at lower at% of Sn. The values of parameters H{sub R}, H{sub w}, and S indicate that Glass forming ability (GFA) decays with an increase in Sn content.
