CALPHAD-type theoretical assessment of the Pb-Se-Sn system was carried out. This assessment is part of a larger project aimed at developing an Ag-Pb-Se-Sn-Te thermodynamic database which should serve for the development of materials for thermoelectric applications. The experimental results from the literature were used but they are quite sparse and significant inconsistencies have been found between experimental data published by various authors, especially in the Se-rich regions. In general, a reasonable agreement was obtained for the theoretical and experimental sections of the phase diagram and for the enthalpies of mixing of the liquid phase in the region with low selenium content, but the agreement is rather qualitative in the Se-rich region.
