摘要：
Recently porous ceramic membranes have received great interest due to their outstanding thermal and chemical stabilities. In this paper, we investigated whether we could prepare an alumina coating to be deposited over a diatomite-kaolin composite support layer to reliably tailor the permeability by controlling the heat-treatment temperature of the alumina coating. The pore characteristics of an alumina coating on a diatomite-kaolin composite support layer were studied by scanning electron microscopy, mercury porosimetry, and capillary flow porosimetry.
