Abstract: In this study, the transient plane source (TPS) technique was used to measure the thermal conductivity and thermal diffusivity of Se_85-xTe₁₅Sb_x (x = 2, 4, 6, 8, and 10) pellets. These values were then used to determine the specific heat per unit volume of these glasses in the composition range of investigation. It was found that 4 at% of Sb (antimony) results in the critical composition of the alloy, meaning that the system becomes a chemically ordered alloy and maximum thermal stability at that composition.
