摘要：

The solid solution Ba0.5Sr0.5Co0.8Fe0.2O3 - delta was synthesized by the glycol-citrate method. The thermal behavior of the obtained powder was studied by simultaneous thermal analysis in an air flow in the temperature range of 25-1200 degrees C, and the conditions were determined for the heat treatment to obtain the oxide with a given cubic crystal structure of the perovskite type. The obtained powder was assayed and its phase composition and microstructure were investigated by a set of modern methods of physicochemical analysis (X-ray powder diffraction analysis, energy-dispersive X-ray spectroscopy, and IR spectroscopy). It was shown that the proposed synthesis method under the determined conditions is efficient for obtaining the single-phase oxide of the given composition without impurities.
