   The phase equilibria in the Pd-Pb-Te system was studied by the evacuated silica-tube method. The isothermal section was investigated at 400 C. The phase PdTe, the analogue of kotulskite, forms an extensive solid-solution and dissolves up to 30.2 at.% Pb. In the system Pd-Pb-Te, there are two ternary phases: Pd3Pb2Te2, the analogue of pašavaite and Pd71Pb8Te21 not know to occur in nature. Pašavaite forms a stable association with kotulskite solid-solution in a compositional range from 25 to 30 at.% Pb and altaite. The phase Pd71Pb8Te2 forms stable assemblages with zvyagintsevite, telluropalladinitess, kotulskitess, and Pd20Te7ss. Thus, such associations can be expected to occur in nature. Apart from ternary phase the following binary phases: PdPb2, PdPb, Pd13Pb9, Pd5Pb3, Pd3Te2, Pd20Te7, and Pd17Te4 can be expected to occur in nature in close association with other platinum-group minerals, in particular with known minerals of the system Pd-Pb-Te.
