Y. Tsuruta et al., Mixed electronic-oxide ionic conductor of Fe-doped La(Sr)GaO3 perovskite oxide for oxygen permeating membrane, EL SOLID ST, 4(3), 2001, pp. E13-E15
Oxygen permeating property of Fe doped LaGaO3 based perovskite oxide was in
vestigated in this study. Fe doped La1-xSrxGaO3 exhibits high total conduct
ivity (similar to 10(3) S/cm) and high oxygen permeation rate. In particula
r, 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 memb
rane thickness. (C) 2001 The Electrochemical Society.
