Abstract：High strength and high porous alumina ceramic membrane was prepared with the raw material of average particle size of 20 μm α- Al2O3, the solvent of deionized water, the binding agent of kaolin and silica fume. The effect of binding agent on phase composition, microstructure, porosity and compressive strength of ceramic membranes were discussed. The results showed that alumina ceramic membranes with high porosity ranging from 36. 3%- 36. 7% were prepared by adjusting the content of binding agent. The compressive strength of the sample was between 59 to 105. 9 MPa, which showed a first increasing and then decreasing trend with the content of binding agent increasing and reached 105. 9 MPa at the 7. 5% (mass fraction) binding agent.
