摘　　要：在总结文献和实验数据的基础上提出了选择高性能钙钛矿型氧化物混合导体透氧膜材料的策略 ,应用此策略对几种钙钛矿型透氧膜材料的性能作了合理的解释 ,并在此基础上开发了具有高透氧量的Ba0 .5Sr0 .5Co0 .8Fe0 .2 O3 -δ材料和具有长期稳定性的BaCo0 .4 Fe0 .4 Zr0 .2 O3 -δ材料 .A series of methods for selecting perovskite-type oxides used as mixed-conducting membranes for oxygen separation were reviewed according to the literatures and experimental data.The oxygen permeability of several perovskite-type membranes was properly interpreted.Based on these strategies,the membrane made of Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3-δ with high oxygen permeability and the membrane made of BaCo 0.4 Fe 0.4 Zr 0.2 O 3-δ whth high stability were devloped successfully.
