Abstract

The ternary system Nd2S3–Ga2S3–EuS was studied by physicochemical analysis methods. The projection of the liquidus surface was constructed, and the boundaries of the glass formation region were found. It was determined that the ternary system consists of ten fields of primary crystallization of individual phases and the glass formation region. The thermolysis of the synthesized glasses was investigated, and their IR spectra were recorded. In the course of the thermolysis in an inert atmosphere, the glass (Ga2S3)0.70(Nd2S3)0.25(EuS)0.05 softens at 1010 K and then crystallizes at 1110 K. The mass loss proves that the exothermic events observed in the temperature range 1145–1225 K are related to stage-by-stage glass decomposition.
