Abstract
In the present work we report physico-chemical properties in novel Se78 – xTe20Sn2Sbx (x = 0, 2, 4 and 6) glassy system prepared by melt quench technique. Various physico-chemical properties such as co-ordination number, lone pair of electrons, number of constraints, density, molar volume, compactness, mean bond energy, cohesive energy, glass transition temperature and covalence character has been estimated. The compositional dependence of aforesaid physico-chemical properties has been investigated. It has been observed that average number of constraints, mean bond energy, glass transition temperature are found to increase where as number of lone pair of electrons and electro negativity decreases with increases of Sb content in the Se78 – xTe20Sn2Sbx (x = 0, 2, 4 and 6) glassy alloys.
