Alloys in the As2S3-TlAs2S2Se2 section of the As2S3-As2Se3-TlS ternary system were studied and a phase diagram was constructed using physicochemical methods (differential thermal analysis, microstructural analysis, X-ray powder diffraction, also microhardness and density measurements). The diagram in the As2S3-TlAs2S2Se2 section is a non-quasi-binary diagonal section of the As2S3-As2Se3-TlSe quasi-ternary system. It was found that all the alloys in the section under ordinary conditions are obtained in the vitreous state. At low As2S3 concentrations in the section, solid solutions form up to 2.5 mol %, and at low TlAs2S2Se2 concentrations, their extent is 3 mol %.
