Abstract
Porous ceramic membranes have recently attracted great interest due to their outstanding thermal and chemical stabilities. In this paper, we report the results of our efforts to determine whether we could prepare an alumina coating to be deposited over a diatomite-kaolin composite support layer that could control the largest pore size and permeability. In addition, we determined under what conditions such an alumina coating over a diatomite-kaolin composite support layer could be prepared with minimum micro-crack generation during heat-treatment. The pore characteristics of an alumina coating on a diatomite-kaolin composite support layer were studied by scanning electron microscopy and capillary flow porosimetry.
