Abstract
An improved method for preparing porous mullite ceramic from Pickering emulsions stabilised by hetero-aggregate of oppositely charged fumed oxide particles. The method uses oppositely charged fumed oxide nano-particles (silica and alumina) to stabilize oil-in-water Pickering emulsions wherein the stabilized Pickering emulsions can be used as a template for preparing porous mullite material. An optimised Pickering emulsion template that is stabilised with fumed oxide nano-particles (silica and alumina) is used to produce a green body that is transformed into solid porous material with a controlled porosity and pore size by sintering.
