• The phase diagram of the quasiternary system (Snt Pb )(S,Te ) for 900 K is determined by X-ray diffraction and by electron microprobe analysis. Moreover, the free enthalpy faces g(k, I) for the phases with cubic rocksalt structure (cub) or with the orthorhombic SnS structure (orh) are calculated from the interaction parameters and from the orh → cub transition data of the 4 quasibinary subsystems. The interaction parameters are also used to calculate the termodynamic factor for interdiffusion along quasibinary sections through the phase square and to calculate the energies of four-particle clusters. By application of the cluster model one obtains information on the local environment of the mixing particles and on the cluster processes that have effect upon interdiffusion
