Abstract

Preparation of porous ceramic body foamed by microbe is prone to structure defects such as inequality of pore size and distribution, crack, contraction deformation, etc. Four-level orthogonal tests based on three improving factors such as water content(WC) and carboxymethyl cellulose (CMC) and stirring time(ST) were carried out to improve the method of preparing porous ceramic body foamed by microbe at ordinary tempreature. It is concluded that water content is the key improving facor followed by stirring time and CMC content, and the optimized formula could be A3B3C1 or A3B4C2.
