Ceramic Porous Material

Porous ceramics are resistant to most acids except for hydrofluoric acid and phosphoric acid.

Ceramic porous material.

In alkaline solutions porous ceramics are resistant up to ph9. 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. Combining tightly toleranced pores with unique ceramic material properties enables applications not feasible before. 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.

Up to 1000c for porous ceramic limited only by sealants gaskets and or hardware materials. Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. 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. Porous ceramics are often used for chemical filtration and fluid separation.

A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Porous ceramics are categorized as those ceramics having high percentage porosity between 20 and 95. It is also resistant to organic solvents.
