The physico-chemical interaction in the Tl₂Se–SnSe–PbSe quasiternary system was investigated by differential thermal analysis and X-ray diffraction in combination with mathematical modeling. Diagrams of the phase interaction, the projection of the liquidus surface and an isothermal section (520 K) were constructed. The quasiternary system is of the invariant eutectic type. The three-dimensional one-, two- and three-phase regions present in the Tl₂Se–SnSe–PbSe system are described.
