Ceramic Porous Materials

Combining tightly toleranced pores with unique ceramic material properties enables applications not feasible before.

Ceramic porous materials.

Developing new ceramic materials is an exciting challenge as we need to understand the complexities of how they are made and used. 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. Dear colleagues modern porous ceramic materials can be used for a wide range of possible applications such as catalyst support structures filter heat or acoustic insulation scaffolds or lightweight structures. A key part of our r d work is to meet with customers to better understand their needs which then allows us to quickly develop products that deliver better performance.

A ceramic is any of the various hard brittle heat resistant and corrosion resistant materials made by shaping and then firing a nonmetallic mineral such as clay at a high temperature. D 2 nm. Foams are also called cellular ceramic materials because their structure can be represented by a lattice of a repeatable unit called cell. Custom coorstek porous ceramics can be tailored from 0 1 100 µm with precision tolerances and a variety of ceramic material options.

These properties have many uses comprehending macroscaled devices mesoscaled materials and microscaled pieces. D 50 nm. Up to 1000c for porous ceramic limited only by sealants gaskets and or hardware materials. Materials an international peer reviewed open access journal.

Ceramic foams are a special class of porous materials included of large voids with linear dimensions in the range between 10 and 5 mm. 50 nm d 2 nm and macropores. These materials often present low fixed and well defined thermal conductivity figures. Common examples are earthenware porcelain and brick.

Porous ceramics are resistant to most acids except for hydrofluoric acid and phosphoric acid. The crystallinity of ceramic materials ranges from highly oriented to semi crystalline vitrified and often completely amorphous e g glasses. Ceramic foams are porous brittle materials with closed open celled structures or partially interconnected porosity. The objective here is not to carry out an extensive revision of the fracture of brittle porous.

It is widely known that increasing interest in porous ceramics is due to their special properties which comprise high volumetric porosity up to 90 with open or closed pores and a broad range of pore sizes micropores.
