Abstract
The results on the structural and thermal stability of different modifications of solid solutions Bi4V2 − x Fe x O11 − δ (BIFEVOX), where x = 0.05–0.6, and Bi4V2 − x Cu x/2Ti x/2O11 − δ (BICUTIVOX), where x = 0.025–0.50, are shown. The stability is assessed by varying the thermodynamic parameters of the medium and also the time parameters with the use of modern methods, namely, the high-temperature X-ray diffraction analysis, the differential scanning calorimetry, and the dilatometry. The γ-modification of BIFEVOX is shown to be stable in a wide range of temperatures and oxygen partial pressures.
