Phase equilibria in the section Tl₄PbTe₃-Tl₉SmTe₆-Tl₉BiTe₆ of the Tl-Pb-Bi-Sm-Te system were determined by combination of differential thermal analysis, powder X-ray diffraction methods as well as microhardness measurements. The phase diagrams of the boundary systems Tl₄PbTe₃-Tl₉SmTe₆, Tl₉SmTe₆-Tl₉BiTe₆, isothermal section at 820 and 840 K, some isopleth sections and as well as liquidus and solidus surfaces projections, were plotted. Unlimited solid solutions, which crystallize in Tl5Te3 structure type were found in the system at the solidus temperatures and below.
