Abstract
In the present paper , we have studied the effect of Ge addition on the physical properties of Se-Sn - Pb chalcogenide ma - terial. The necessary physical parameters which have important role in determining the structure and strength of the material viz. constraints, coordination number etc. ha ve been calculated. The increasing trend has been found in cohesive energy, heat of atomization and mean bond energy. The glass transition has been studied using the Tichy-Ticha and Lankhorst approaches, which also increases with the increasing Ge contents. The increase in these physical parameters is due to the increasing covalent character in the material.
