We derive analytical expressions for the free energy of mixing of (YbTe)х(PbTe)1–х and (YbTe)х(SnTe)1–х solid solutions in the temperature range 600–1095 K and accurately determine the location of their phase boundaries. Т–х–у relations for the solidus surface and the spinodal decomposition of solid solutions in the pseudoternary system YbTe–PbTe–SnTe are found.
