Abstract

Oxygen permeating property of Fe doped LaGaO3 based perovskite oxide was investigated in this study. Fe doped La1-xSrxGaO3 exhibits high total conductivity (∼103 S/cm) and high oxygen permeation rate. In particular, the highest total conductivity and oxygen permeating rate were attained at La0.7Sr0.3Ga0.6Fe0.4O3. At this composition, oxygen permeation rate from air to He was as high as 2.5 cm-2/min · cm-2 at 1273 K and 0.3 mm membrane thickness.
