Abstract:  Mullite fiber porous ceramic was prepared with acid aluminum phosphates as binder and pressure liquid-displacement forming, with porosity of 96%. Properties of Lag0.8Sr0.2CoO3 supported on Mullite fiber porous ceramic were studied with vacuum impregnation. Relations between impregnation times, impregnation numbers, and support weight were observed.The optimal impregnation time was 60 minutes and the optimal impregnation number is 2. Structural frame was charaterazed with SEM photos. In the end, mullite fiber porous ceramics as a good catalyst carrier is possible.

Keywords:  mullite fiber, porous ceramics, catalyst carrier, property, characterization
