  • Abstract
    Perovskite hollow fibre membranes of the chemical composition BaZrxCoyFezO3−δ (BCFZ) have been developed using a phase inversion spinning process followed by sintering. The BCFZ hollow fibre membranes show an O2 flux of 7.6 ml/min/cm2 at 900 °C which is the highest value so far known. From the Wagner theory it follows that the O2 transport through thin walled perovskite hollow fibre membranes is controlled by both vacancy diffusion and interface reactions.
