| Popis: | A series of tellurides FexTi1−xTe1.65 (x = 0, 0.1, 0.2 …, 1.0) synthesized at 850°C were studied by X-ray phase and X-ray fluorescent analysis and Mossbauer spectroscopy on 57Fe. In this series two solid solutions are formed: phases I and II with homogeneity regions within the limits of 0 ≤ x ≤ 0.3 and 0.9 ≤ x ≤ 1.0, respectively. Iron in this series exists in two various states: Fe2+sym and Fe2+asym as differentiated from the series of tellurides FexTi1−xTe1.45 where three states of iron Fe2+sym, Fe2+asym, and Fe0 were found. On passing from FexTi1−xTe1.45 to FexTi1−xTe1.65 the number of formed phases decreases, and phase relations become simpler. The absence of Fe0 from phase I of tellurides FexTi1−xTe1.65 can point to the fact that TiTe1.45 and TiTe1.65 belong to different homogeneity regions. |
