The process of adding the pore-forming agent can be applied to porous ceramics with complex shapes, but the pore size is difficult to control, and the process is not suitable for preparing the porous ceramics with high porosity. The extrusion forming process is applied to manufacturing long and thin porous ceramics, the size and the shape of pores can be accurately controlled, but the method is not suitable for preparing the porous ceramics with complicated pore diameters.
