Mechanochemical syntheses of antimony selenide, tin selenides and two tin antimony selenides

Abstract Sb 2 Se 3 , SnSe, SnSe 2 , SnSb 2 Se 4 , and Sn 2 Sb 6 Se 11 were prepared from powdered elements in a planetary ball mill. The progress of the reactions was investigated in situ by difference thermoanalysis and ex situ by X-ray analyses. SnSb 2 Se 4 , and Sn 2 Sb 6 Se 11 are probably both positioned in the homogeneity region of the only ternary compound of the system Sn–Sb–Se.
