Abstract
Chalcogenide glasses from the Ag 2Te–As 2Se 3–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”— E ¯ c and E ¯ rm , as well as the average heteropolar bond energy E hb, the degree of “cross-linking/atom” P p and the radial bond strength were determined. The correlation between the composition and properties of the Ag 2Te–As 2Se 3–CdTe glasses was established and comprehensively discussed.
