Ce2Se3-Sb2Se3-Bi2Se3 KVAZİÜÇLÜ SİSTEMİNDƏ FAZAƏMƏLƏGƏLMƏ
Xülasə
Based on the literature data, as well as the results obtained by the methods of physicochemical analysis, the character of phase formation in the Ce2Se3-Sb2Se3-Bi2Se3 quasi-ternary system was determined. The phase diagrams of a number of internal sections (Sb2Se3-CeBiSe3, Ce2Se3-CeSb1,5Bi1,5Se6, Bi2Se3-CeSb1,5Bi1,5Se6, CeSbSe3 -CeBiSe3), the isothermal section at 300 K, and the projection of the liquidus surface were constructed, the types and coordinates of non- and monovariant equilibria were obtained. The existence of six ternary compounds, S1(Ce8Sb2Se15), S2(Ce6Sb4Se15), S3(CeSbSe3), S4 (CeBiSe3), S5( CeSb1,5Bi1,5Se6 ) and S6 (Ce8Bi2Se13), as well as regions of solid solutions based on the initial Sb2Se3 , Bi2Se3 , as well as S5 compounds was shown.
