Abstract
Based on the results of the DTA and X-ray phase analysis, the phase equilibria in the BiTeI–BiSI system were studied and the T–x phase diagram was constructed. It was established that the system is stable in the subsolidus area and there are ~7–8 mol % and ~5 mol% solid solution areas based on BiTeI and BiSI compounds at room temperature, accordingly. In2016 general, the system is non-quasibinary. Bi19 S27I3 (0–33 mol % BiTeI) and tetradymite-Bi2Te2 S (33–83mol% BiTeI) phases pri-marily crystallize from the liquid phase in the wide composition ranges.
