Abstract
In the present work, the results of high-temperature oxygen desorption from oxide with mixed conductivity composed of SrCoO3 – δ obtained via original quasi-equilibrium oxygen release technique were shown. Measurements were carried out with a characterized powder sample in a tubular reactor. The equilibrium phase diagram of the oxide in the temperature range and partial pressure of oxygen: 600–850 оC and 0.2–6⋅10-5 atm, respectively, was obtained. With the help of literary data, correlation of phase diagram regions with their corresponding structures was carried out.
