To determine the area of glass formation in the system As2S3-ErS were synthesized alloys in the range of concentrations 0-30 mol. % ErS. The methods of physico-chemical analysis of differential-thermal (DTA), X-ray phase (RFA), microstructural (MCA) analyzes, as well as the measurement of microhardness and density determined the area of the glass and studied them physicо-chemical propertes. It is established that in the system As2S3-ErS on the basis of As2S3 during slow cooling the area of the glass reaches 17 mol. % ErS. Alloys in the concentration range 20-30 mol. % ErS are glass-crystalline. In the system at room temperature solid solutions on the basis of As2S3 are distributed up to 2.5 mol.% ErS, and on the basis of solid solutions ErS are practically not installed.
