The isothermal section at 620 K, the liquidus projection and six polythermal sections of the phase diagram of the system Cu₂Se–SnSe₂–Sb₂Se₃ were constructed based on X-ray diffraction, microstructure analysis and differential thermal analysis. The coordinates of the invariable points were determined. No quaternary or new ternary phases were observed in the system. The solid solutions based on the compound Cu₂SnSe₃ did not exceed 2%.
