New chalcogenide glasses in the Ag2Te–As2Se3–CdTe system Original Research Article

Chalcogenide glasses from the Ag2Te–As2Se3–CdTe system were synthesized. The basic physicochemical parameters such as density (d ), microhardness (HV ) and the temperatures of phase transformations (the glass transition T g, crystallization T cr and melting T m) were measured. Compactness and some thermomechanical characteristics such as volume (V h) and formation energy (E h) of micro-voids in the glassy network, as well as the module of elasticity E were calculated. The overall mean bond energy 〈E 〉, the mean coordination number Z , the mean bond energy of the average cross-linking/atom and the average bond energy per atom of the “remaining matrix”—View the MathML sourceE¯c and View the MathML sourceE¯rm, as well as the average heteropolar bond energy Ehb, the degree of “cross-linking/atom” Pp and the radial bond strength were determined. The correlation between the composition and properties of the Ag2Te–As2Se3–CdTe glasses was established and comprehensively discussed.
