The porous ceramic support was prepared from cordierite by adjusting the phase composition, grain size of aggregate, additions of pore-forming material and binder. The porous ceramic support had excellent chemical stability and relative high strength with a porosity of 48％and pore size of 128μm. Factors that affected the properties of the support material were analyzed. The pore size of the porous ceramic support was directly proportional to the grain size of the aggregate around firing temperature. The strength of the support material increases with a rise in amount of the binder and firing temperature. The porosity of the support material increases while the strength decreases with a rise in amount of the pore-forming agent.
