The porous alumina ceramic can be used as catalyst carrier materials, filtering materials and high refractory materials. There are a lot of methods to produce porous alumina ceramics. Protein foaming-consolidation method for preparing porous alumina was used in this paper. The protein which is friendly to environment is both consolidating and foaming agent.
The slurries were prepared with different solid loadings, water and foaming agent. The effect of amount of foaming agent, stirring time and the spee...
