摘　　要：浸渍相转化法可以制备非对称结构的陶瓷中空纤维膜.本文讨论了陶瓷中空纤维膜的发展情况,并着重探讨了各因素对膜孔结构的影响.大量陶瓷粉体存在情况下的相转化机理,孔结构与力学强度的平衡问题,是目前需要重点关注的两个问题.有效调节孔结构,保证其力学性能可以实现陶瓷中空纤维膜在分离和纯化、固体氧化物燃料电池、膜催化器和膜反应器等方面的广泛应用.Ceramic hollow fiber membranes（CHFM） with an asymmetric structure can be fabricated by the method nonsolvent induced phase separation（NIPS）.The paper reviews the progress and tendency of the ceramic hollow fiber membranes using NIPS technic,especially on the influence of factors on the structure of hollow membranes.The discussion on the mechanism of phase inversion in the systems containing much ceramic powders,with the balance between porous structure and mechanical strength,are two important issues of requiring concern.Through structure’s controlled effectively and mechanical strength preserved,hollow fiber membranes can be widely applied in the fields of separation and purification,solid oxide fuel cell（SOFC）,membrane contactors and reactors.
