Abstract : Differential Scanning Calorimetry (DSC) has been used as to investigate the specific temperatures of glassy Se90- xTe5Sn5Inx (0≤x≤9) alloys in the crystallization region at various heating rates under non-isothermal conditions. This study examines specific heats of glassy Se-Te-Sn-In network for crystallization region. The observed specific heats Cpl (before) Cpa (after) and ΔCpc (difference of Cpa and Cpl), for crystallization region were carried out. The study also explored the composition-dependent of glassy Se-Te-Sn-In system, variability with different concentrations of In. All specific heats change with different Indium concentrations, and most at a composition of 9 at.wt. % of In. The variations of specific heats have been explained on the basis of atomic weights and room temperature values of Cp for the elements Se and In.

Keywords : Specific Heat; Multi-Component Chalcogenide Network; Crystallization Temperature; Average Coordination Number; Differential Scanning Calorimetry (DSC).
