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.
期刊介绍：
Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and
appears with twelve issues per year. The journal is open to letters, short communications and breakings news
inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in
structure, properties and applications, as well as those covering special properties in nano-structured
chalcogenides are admitted.
