Study of high-temperature oxygen permeability in Sr1 − xLaxCo0.8 − yNbyFe0.2O3 − z perovskites
The oxygen permeability of ceramic SrCo0.8 − yFe0.2NbyO3 − z (0 ≤ y ≤ 0.2) and La0.3Sr0.7Co0.6Fe0.2Nb0.2O3 − z disc membranes as a function of temperature and oxygen partial pressure was studied. Kinetic analysis was performed based on the experimental data on oxygen permeability as a function of oxygen partial pressure.
