Abstract：

A porous supportconsisting of spherical or ellipsoidal alumina as aggregate and a certain number of sintering aids was prepared by dry-pressing process. The effect of parameters of powder particle（particle shape,particle size distribution） on the porous support was investigated. The support, comprising ellipsoidal alumina as aggregate and 0.6wt.% of sintering aids, sintered at 1600℃,possessed great potential application with 3.34μm in pore size,34.8% open porosity as well as >80 MPa mechanical strength. The pure water flux value was above 50 m3• m-2•h-1•bar-1.
