✦ Synopsis

Perovskite hollow fibre membranes of the chemical composition BaZr x Co y Fe z O 3-Ξ΄ (BCFZ) have been developed using a phase inversion spinning process followed by sintering. The BCFZ hollow fibre membranes show an O 2 flux of 7.6 ml/min/cm 2 at 900 β€’ C which is the highest value so far known. From the Wagner theory it follows that the O 2 transport through thin walled perovskite hollow fibre membranes is controlled by both vacancy diffusion and interface reactions.

The mixed ion and electron conducting oxides of SrCo 1-y Ta y O 3-Δ± (0 ≀ y ≀ 0.3) powders were prepared by solid state reaction. By doping 10 mol% of tantalum on the B-site of SrCoO 3 , the cubic perovskite structure of the SrCoO 3 is stable and a high oxygen permeation flux is achieved. The phase s
