Ceramic Porous Material

Porous ceramics are categorized as those ceramics having high percentage porosity between 20 and 95.

Ceramic porous material. Porous ceramics are often used for chemical filtration and fluid separation. Combining tightly toleranced pores with unique ceramic material properties enables applications not feasible before. It is also resistant to organic solvents. Porous ceramics are resistant to most acids except for hydrofluoric acid and phosphoric acid.

In alkaline solutions porous ceramics are resistant up to ph9. Up to 1000c for porous ceramic limited only by sealants gaskets and or hardware materials. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramic foam is an important part of porous ceramics and the open cell type of ceramic foam which is a new type of highly porous ceramics has a three dimensional reticulated structure with connective pores resulting in great specific surface area high fluid contact efficiency and a small loss of fluid pressure 26 27.

Porous ceramics can replace metal plastic or fiber based components providing equal or higher levels of performance and extending the useful component life under harsh conditions. Custom coorstek porous ceramics can be tailored from 0 1 100 µm with precision tolerances and a variety of ceramic material options. These materials composed of at least two phases like solid ceramic phase and the gas filled porous phase the gas content of these pores usually regulates itself to the environment as an exchange of gas with the environment is possible through pore channels.
