Abstract: Selenium (Se) and tellurium (Te) based glasses have unique physical and chemical characteristics that can be manipulated with by the addition of metal alloys. In this study, the thermophysical properties of Se80Te20 and Se80Te10M10 (where M = cadmium (Cd), indium (In), and antimony (Sb)) chalcogenide (containing one or more S, Se, or Te) glasses are investigated to test their use in industrial applications. The transient plane source (TPS) method was used to measure the thermal conductivity, thermal diffusivity, and specific heat of glassy Se80Te20 and glassy Se80Te10M10. Results showed that the glassy Se80Te10In10 alloy had the highest thermal conductivity values, indicating that In is more thermally conductive than Cd and Sb.
