ceramics is a kind of ceramics with high porosity, which is necessary for application, designed and retained intentionally. The skeleton of ceramics is usually called "matrix" or "frame". There are two main types of pore structures: bubble (closed pore) structure and network (open pore) structure. According to the characteristics of pore structure, porous ceramics can be divided into four types: porous ceramics with complex fiber network; Porous ceramics; Reticulate or open cell structure porous ceramics and membrane porous ceramics.
