Abstract

Differential Scanning Calorimetry (DSC) is performed at different heating rates under non-isothermal conditions to study the heat capacities studies of glassy Se75Te15- XCd10InX(x=0, 5,10and 15) alloys.Heat capacities of Se75Te15-XCd10InX(x=0, 5,10and 15) chalcogenide glasses at glass transitions (Tg) and crystallisations temperatures (Tc) werementioned in this work. The evaluated endothermic (ΔCpg) and exothermic (ΔCpc) heat capacities of Se-Te-Cd-In system varies with alloying concentrations and maximum at threshold composition (5 at wt.% of In). This could be explained on the basis of chemical bond theory of the solids.
