Abstract

Oxygen permeating property of Fe doped LaGaO₃ based perovskite oxide was investigated in this study. Fe doped La_1-xSr_xGaO₃ 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 La_0.7Sr_0.3Ga_0.6Fe_0.4O₃. 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.
