Cellular structures

Highly porous ceramics, together with metals and plastics, are currently attracting a significant scientific and industrial interest, with research activity focusing on processing developments, finding novel applications and the study of the relationships between microstructure and properties. Cellular ceramics constitute a specific class of porous materials containing a high level of porosity (typically > 70 vol%) with a structure consisting of an array of hollow cells. The reason for this interest is certainly related to the special properties that a material possesses when manufactured into a highly porous cellular solid. This chapter will review the properties, fabrication methods, morphology and applications of cellualr ceramics
