Silicon carbide ceramic membrane and preparation method thereof
The invention relates to a silicon carbide ceramic membrane and a preparation method thereof, belonging to the field of preparation of porous ceramic materials. The preparation method comprises the following steps: mixing SiC aggregate, a sintering aid, a toughening aid and a high-molecular binder in proportion; and then successively carrying out stirring and ball milling, molding, high temperature sintering, coating and sintering so as to obtain the porous silicon carbide ceramic membrane. The silicon carbide ceramic membrane prepared in the invention has the advantages of high porosity, great toughness, low sintering temperature, thermal shock resistance, etc., and can be widely applied to the field of high temperature gas-solid separation.
