Flash method technique is widely used to measure the thermal diffusivity, specific heat capacity, and thermal conductivity of materials. Chalcogenide glasses have been attracting much attention despite their weak binding properties compared with the conventional widely known oxide glasses. The objective of this study is to set an experiment based on flash method technique to assess the specific heat capacity, thermal diffusivity, and thermal conductivity of bulk Se 85−x Te 15 S x (x = 5, 15, 20, and 25 at.%) from room temperature to 175 °C. The present work is considered as a further addition to the previously performed work that investigated the thermal analysis conducted on ternary system Se 85−x Te 15 S x . A calibration for flash method experiment was done using a reference sample, where the obtained results of calibration were compared to other reported data and the DSC results of the investigated samples were taken into consideration during the analysis.
