Abstract
The analysis of the temperature change of softening of chalcogenide glass with ion conductivity by silver from the content of its chalcogenides is given. Explanation of peculiarities of temperature change of softening of glass on the basis of chalcogenides of silver is offered by coexistence of covalent bonds of silver-chalcogen (Ag-Ch) and metallophilic bonds of silver-silver (Ag-Ag). The large number of systems considered demonstrates the general regularity, which allows to assume, that the degree of connectivity of silver in the HHS mesh due to formation of it in addition to covalent metal-philic bonds actually significantly exceeds its formal oxidation degree.Metallophilic interactions are expected to influence not only the softening temperature, but also the variation of many other important properties in the glass, including the ion transfer mechanism by silver.
