Essay

Using physico-chemical analysis methods, phase equilibriums in the following systems were investigated: Cu2Se-Ga2Se3-GeSe2 at 770 K, Cu2X-R2X3-GeX2, R-La, Sm, X-S, Se at 870 K. The crystal structure of 16 compounds were determined, using X-Ray powder and single crystal methods. 12 new compounds were synthesized for the first time. They represent 7 structural types, 4 of them are new. The temperature dependence of magnetic susceptibility showed that Ce3Ge1.47Se7, Sm3CuGeS7 and Sm3CuGeSe7 compounds are paramagnetics.
