New chalcogenide glasses in the Ag2Te–As2Se3–CdTe system

Abstract Chalcogenide glasses from the Ag 2 Te–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 ¯ 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 2 Te–As 2 Se 3 –CdTe glasses was established and comprehensively discussed.
