PHYSICO-CHEMICAL INTERACTION IN THE BiSI–BiTeI SYSTEM
E.J.Ahmadov

Based on the results of the DTA and X-ray phase analysis, the phase equilibria in the BiTeI–BiSI system were studied and the Tx 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 S27I(0–33 mol % BiTeI ) and tetradymite-Bi2TeS (33–83mol% BiTeI ) phases primarily crystallize from the liquid phase in the wide composition ranges
