We present the results of calculations of the low-temperature part of the liquidus and solidus of Pb/sub 1-y/(Te/sub 1/x/Se/sub x/)/sub y/ with the chalcogen content y less than or equal to 0.10. The phase equilibria were described with the help of the model of simple regular solutions with renormalized entropies of melting of the binary compounds. The interaction parameters of the components in the solid phase /sup ..cap alpha../PbTe-PbSe/ was determined taking into account the ratio z/x = 1.30 of the Se concentrations in the solid and liquid phases at 773 K. The interaction parameter in the liquid phase ..cap alpha../sub Te-Se/ for small values of y does not significantly affect the computational results.
