Roentgenographic investigation of solid-phase equilibria in the PbSe-AgSbSe2system

The solid-phase equilibria in the 2PbSe-AgSbSe2system were studied by using the powder X-ray diffraction method. It is established that the system is characterized by the formation of ~60 mol% solid solutions basedon AgSbSe2.Solubility based on PbSe is about 3mol%. The cubic lattice parameters of solid solutions are defined.
