Pb-Se-Te ternary system is of significant importance for thermoelectric applications. However, no systematic study of its phase diagram has been carried until now. Samples of Pb-Se-Te ternary alloys were prepared, their phase equilibrium phases were determined, and the Pb-Se-Te isothermal sections at 350 degrees C and 500 degrees C were proposed based on the experimental results. No ternary compounds were found. There is one three phase field, Pb(Se,Te)+liquid(Se,Te)+(Se,Te) at 350 degrees C and no three phase field at 500 degrees C. PbSe and PbTe form a continuous solid solution at both temperatures.
