Abstract TheT — x phase diagram of the pseudobinary system PbTe-As2Te3 was constructed from DTA data and results of X-ray diffraction analysis and electron-probe microanalysis. No new compound was found in the system PbTe-As2Te3. The phase diagram of this system is of an eutectic type with an eutectic temperature of 350±5°, the eutectic composition corresponding to 10 mole% PbTe. Two solid phases with compositions near to As2Te3 and PbTe, respectively, coexist in the system below the eutectic temperature. The solubility of PbTe in As2Te3 is smaller than 2 mole% PbTe, and that of As2Te3 in PbTe is smaller than 0.5 mole% As2Te3 at 290°.
