AbstractSubstitution effects of Ga and Al for Fe in (BaxSr1-x)0.98FeO3-δ were studied with respect to crystal structure, conductivity and oxygen permeability. The solubility limits of Ga and Al in (BaxSr1-x)0.98Fe1-yMyO3-δ (M=Ga, Al) were between 20 and 30 mol%. The substitution of Ga and Al caused decreases in electronic and oxide ionic conductivities (mixed conductivities) but the enhancement of the reduction tolerance. Sintered membranes of the Ga- and Al-substituted oxides showed oxygen permeability under the He/air oxygen partial pressure gradient and were stable under the condition of methane partial oxidation at 900 °C.
