Influence of Metallophilic Interactions on Physicochemical Properties of the Ion-Conducting Glass System (1 – x)(0.27Sb2Se3–0.73GeSe2)–xAg2Se

Abstract

It is discussed how the silver selenide concentration in glasses of the chalcogenide system (1 ‒ x)(0.27Sb₂Se₃–0.73GeSe₂)–xAg₂Se affects their plasticity, the relationship between microhardness and the glass transition temperature, and the binding energy of metal atoms in these glasses. Attention is focused on the many-fold increase in plasticity with an increase in the silver selenide content in chalcogenide glasses. These effects are associated with the formation of the metallophilic silver–silver interactions. The results of impedance measurements supplement the studies because the metallophilic interactions in chalcogenide glass can exert a strong effect on the glass transition temperature and many other important properties including the mechanism of electronic and ionic conduction.
