Resumo

The aim of this work is to synthesize and study the properties of the compound Y2Fe4/3W2/3O7, and pyrochlore-like solid solutions in the Y2O3–Fe2O3–Ta2O5–WO3 system. A method for obtaining Y2Fe4/3W2/3O7 has been developed based on the citrate method. It has been established for the first time that the compound has a layered pyrochlore-like structure described by sp. gr. R3. A study of the heat capacity of Y2Fe4/3W2/3O7 showed that, unlike Y2FeTaO7, the compound does not have polymorphic transitions in the entire temperature range of 25–1460°C. The existence of a continuous solid solution xY2FeTaO7–(1–x)Y2Fe4/3W2/3O7, as well as a limited solid solution xY1.85Fe1.15TaO7–(1–x)Y2Fe4/3W2/3O7, where x = 0.7–1, is shown. It was found that a solid solution of Y2Fe4/3+xW2/3O7 is not realized. The IR and Raman spectra of synthesized solid solutions are considered. The position of their absorption edge is determined.
