The paper reports the pressure-induced phase transitions observed in ternary PbTe and PbSe compounds (Pb1-xSnTe, Pb1-xMnxTe, Pb1-xSnxSe) and non-stoichiometric PbTe ones (Pb0.55Te0.45, Pb0.45Te0.55) at room temperature in the range of 0 to 14 GPa by means of angle-dispersive X-ray diffraction (ADXRD). The structure of the intermediate high-pressure phase appearing above ∼6 GPa for all PbTe-based compounds was established to be Pnma (orthorhombic), like in binary PbTe. The patterns of the intermediate high-pressure phase of Pb1-xSnxSe (x = 0.125) were found to correspond entirely neither to GeS nor to orthorhombic Pnma, but the calculated reflections for GeS type were closer to the experimental ones. A model of the phase transformations is discussed.
