Chalcogenide glasses, commonly exhibiting threshold switching, memory switching, and infrared transmission behavior, are investigated intensively for their electrical and optical properties making them useful for versatile potential applications. This work reports the theoretical calculations on the physical parameters of ternary chalcogenide Se-Ge-Bi glasses besides their dependence upon Bi-content. The structure and strength of the material are greatly influenced by the physical parameters. This article attempts to predict the necessary physical characteristics like coordination number, number of lone pair electrons, mechanical constraints, heat of atomization, and cohesive energy for the Se80 – xGe20Bix (x = 0, 4, 8, 12 at. %) glass system. The observed variations in the physical parameters are the result of modifications in the covalent char-acter of the glass system.
