Abstract

The glassy alloysSe69Sn10Ge21-xSbx (where x= 6, 8, 10, 12, 14) are prepared by melt quench technique. The physical parameters have been studied such as average coordination number, number of constraints, floppy mode, Lone pair electron, mean bond energy and glass transition temperature etc.The chemical bond approach has been used to calculate cohesive energy of the samples. The mean bond energy and glass transition temperature has been calculated using Tichy-Ticha Approach. It has been observed from the study that with addition of Sb, the parameters such as average coordination number, mean bond energy and glass transition temperature decreases.
