Abstract. Oxygen permeation through dense Sr4Fe6O13 membranes was found to be limited by the bulk ambipolar conductivity. At 1173K and oxygen partial pressures 10 to 1.01105Pa, ionic conductivity of intergrowth strontium ferrite increases with reducing oxygen pressure, indicating that the vacancy migration mechanism provides a greater contribution to ionic transport in comparison with the interstitial...
