Chalcogenide glasses from the Ag2Te-AS(2)Se(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) over bar (c) and (E) over bar (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 Ag2Te-AS(2)Se(3)-CdTe glasses was established and comprehensively discussed.
