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.

Se75Te15-XCd10InX(x=0、5、10和15)硫系玻璃热容的组分依赖性

采用差示扫描量热法(DSC)在非等温条件下，以不同的升温速率研究了玻璃态Se75Te15- XCd10InX(x= 0,5,10和15)合金的热容。本文讨论了Se75Te15-XCd10InX(x= 0,5,10和15)硫系玻璃在玻璃化转变(Tg)和结晶温度(Tc)下的热容。Se-Te-Cd-In体系的吸热热容(ΔCpg)和放热热容(ΔCpc)随合金浓度的变化而变化，并在阈值组成时达到最大值(在wt.% In时为5)。这可以用固体的化学键理论来解释。

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.
