摘要：
The study discusses the impact of indium on the thermo-physical properties of Se85-xTe15Inx (0 <= x <= 15) glassy alloys. Theoretical predictions of some physical parameters are taken and an effort is made to describe the various trends of the examined physical properties with the addition of indium content. It is observed that the structural parameters, namely coordination number, constraints, heat of atomization and mean bond energy, increase with increasing indium concentration. Experimentally observed and theoretically calculated glass transition temperature (Tg), using Gibbs-Di Marzio relation and an empirical equation formulated by Tichy and Ticha, is increased with the addition of indium. The results indicate that the incorporation of In to the Se-Te system increases the rigidity of this system. However, the theoretically predicted Tg (Tichy and Ticha approach) is not consistent with experimental values.
