Study of High-Temperature Oxygen Release from Strontium Cobaltite in Quasi-Equilibrium Regime
Results of high-temperature oxygen desorption from SrCoO3 – δ-oxide with mixed conductivity composed of obtained using an original quasi-equilibrium oxygen release technique are shown. The measurements are carried out with a characterized powder sample in a tubular reactor. The equilibrium phase diagram of the oxide in the 600–850°C temperature range and partial pressure of oxygen 0.2–6 × 10–5 atm is constructed. With the help of literature data, a correlation of phase diagram regions with their corresponding structures is obtained.
