Abstract
Abstract In this work, the physicochemical, optical properties and stability against crystallization of GaxGey-xS100-y (x=0–8; y = 40–42) glasses are studied. A method for determining the chemical macrocomposition of glasses with an accuracy of 0.02–0.1 at. % based on inductively coupled plasma atomic emission spectroscopy has been developed. It has been established that the glass annealing results in the formation of the phases of germanium monosulfide, germanium disulfide, and gallium sesquisulfide. Crystallization of glasses with a gallium content of 8 at.% occurs with the formation of an additional phase of unknown composition. When the glass-forming GaxGe40-xS60 (x=0–3) glass melts are air-quenched, GeS2 crystals are formed. The transparency of glasses in the 8–15 µm region rises with an increase in the gallium content. Among the studied compositions, GaxGe40-xS60 (x = 0–8) and Ga3Ge38S59 glasses have highest stability against crystallization.
