Orthogonal Preparation and Microscopic Analysis of Porous Ceramic Foamed by Aerogen
(0) Porous ceramics foamed by aerogens with pores of specific characteristics in shape and size can be widely applied in many fields such as biological engineering,enzyme engineering,environmental engineering,etc.However,the Preparation 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 and carboxymethyl cellulose (CMC) and stirring time(ST) were carried out to improve the method of preparing porous ceramic body foamed by aerogens at ordinary temperature.It is concluded that water content is the key improving factor followed by stirring time and CMC content,and the optimized formula could be A3B3C1 or A3B4C2.Microscopic analysis indicates that there are about 107 pores within 100μm2 with diameter below 10μm and about 117 pores within 10000μm2 with diameter range from 20μm to 100μm in the sample.
