Анотация: The physical-chemical properties and thermal decomposition, as well as the IR spectrum of glass compositions (Ga2S3)0.60(La2S3)0.20(Sm2S3)0.20 and (Ga2S3)0.55(La2S3)0.15(Sm2S3)0.30 were examined. It was determined that the glass composition (Ga2S3)0.60(La2S3)0.20(Sm2S3)0.20 at 865 K is resistant to ambient oxygen. In the IR spectrum of the bands of glasses characterizing the Me-S bond, the intensity is increased and shifted to the high-frequency side of the spectrum in comparison with the initial crystal components, which is probably due to the increased covalence of the Me-S bonds.
