Qısa məlumat

Considering the inconsistency of the available literature data on phase equilibria in the SnSe - Sb2Se3 system, the issue was re-examined by differential thermal analysis and X-ray diffraction technique. A new, refined version of the phase diagram was constructed. It was found that the ternary compound Sn2Sb2Se5 and the intermediate γ -phase with a homogeneity region of 48-60 mol% Sb2Se3 are formed in the system, which melting with decomposition by peritectic reactions at 598°С (Sn2Sb2Se5) and 560°С (γ-phase). This area includes stoichiometric compositions of ternary compounds SnSb2Se4 and Sn2Sb6Se11. A comparative analysis of the results obtained with literature data was carried out.
