Abstract: Ceramic hollow fiber membranes have recently attracted considerable attention, due to the high active area/volume ratio provided by its high packing density, thin wall, high permeability and less material consumption. With the application of ceramic membranes in hollow fiber configuration, the separation equipment can be miniaturized. Ceramic hollow fiber membranes have potential applications in various fields, such as porous and dense ceramic membranes for separation, solid oxide fuel cells, microchannel-reactor, and supports of catalysts. This paper summarized the characteristics and progress in preparation methods of hollow fiber ceramic membranes. The emphasis was put on the comparison of different preparation methods. The phase inversion method was cost-effective, since the derived ceramic hollow fiber membranes with self -supported asymmetric structure and thus high permeability can be obtained in one step. The application of phase inversi method could simplify the fabrication process of ceramic membranes and greatly reduce the production cost.
