Consistent interpretation of isotope and chemical oxygen exchange relaxation kinetics in SrFeMoO ferrite.

This paper is devoted to the study of phase composition and kinetic and thermodynamic characteristics of Mo-doped strontium ferrite SrFeMoO (SFM15) under oxygen-conducting membrane working conditions. Single-phase SFM15 with a cubic 3̄ structure was synthesized using a ceramic method. It was shown that the molybdenum introduction stabilizes the perovskite cubic structure over a wide range of oxygen pressures and temperatures, preventing the bulk phase transition at high temperatures.
