Abstract

Substitution effects of Ga and Al for Fe in (Ba_xSr _1-x)_0.98FeO_3-δ were studied with respect to crystal structure, conductivity and oxygen permeability. The solubility limits of Ga and Al in (Ba_xSr_1-x)_0.98Fe _1-yM_yO_3-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 tolerance toward enhanced the tolerance reduction. 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.
