Abstract Chalcogenide glasses are of huge attention due to these intriguing optical and electrical characteristics. The physical parameters of Se90-x Te5 Sn5 Inx (0≤x≤9) glassy alloys have been thoroughly examined in this work. In this system I have theoretical evaluated density (ρ), molar volume (Vm ), lone pair of electrons (LP), average coordination number , number of constraints (Nc ) and mean bond energy for this system. The evaluated values of Vm , LP, and stoichiometry (R) fall with increasing In content or average coordination number. Because indium has a larger atomic mass and stronger bonding properties than selenium, an increase in density was seen as the amount of indium increased. On the other hand, molar volume exhibited a declining trend, suggesting improved structural rearrangement and compactness within the glass network.
