Preparation and application in oil–water separation of ZrO2 α-Al2O3 MF membrane

The composite tubular membranes were prepared by applying suspensions of zirconia particles to form separation toplayerson two different porous a-alumina supports and heating the coated supports to partly sinter the particles of top-layers.The conditions of synthesizing the ZrO2/a-Al2O3 membranes were investigated systematically. The mean pore diameter ofzirconia me..
