The phase equilibria in the CuSbS2-Sb2S3-SbSI compositions intervals of the Cu-Sb-S-I quaternary system have been investigated by differential thermal analysis and X-ray phase analysis methods. The boundary quasi-binary section CuSbS2-SbSI, two internal polythermal sections of the phase diagram, as well as, the projection of the liquidus surface of the system were constructed. Primary crystallization areas of phases, types and coordinates of non-and monovariant equilibria were determined. It was established that, the system is quaternary and belongs to the nonvariant eutectic type. The liquidus surface consists of three distinct regions, each representing the direct crystallization of one of the primary compounds from the melt. These regions are separated by three eutectic curves defining the boundaries between them.
