Synthesis and study of the thermal stability of SrFe1-xM xO3-z (M = Mo, W) perovskites

In the present work, solid solutions of the composition SrFe1 - xM O-x(3 - z),where M = Mo, W and 0 < x < 0.5, are synthesized. The structure of the new materials depending on the composition and on oxygen stoichiometry is studied; the results of high-temperature X-ray diffraction measurements, thermal stability and phase transformations in various environments are presented.
