Анотація In the present paper we have studied the physical properties of Se-Sn-Pb chalcogenide material. The necessary physical parameters which have important role in determining the structure and strength of the material viz. constraints, coordination number, glass transition temperature etc. has been calculated. The decreasing trend has been found in cohesive energy, heat of atomization and mean bond energy. The glass transition has been studied using the Tichy-Ticha approach which also decreases. The decrease in these physical parameters is due to the increase of ionic character in the material.
