Abstract: In addition to a high porosity and specific area, foam Sic ceramic materials possess other
characteristics, for example, low density, good thermal, mechanical, electrical and acoustical properties
All the characteristics make them attractive for a wide range of applications in chemical industry
machinery, bio-field and environmental protection. In this paper, several main fabrication techniques of
foam SIC ceramic materials are summarized, including powder sintering, solid state reaction sintering,
silicon resin pyrolysis and chemical vapor deposition. Some excellent properties of SIC foams, for
example, special three-dimensional reticular structure, fluid resistance, oxidation resistance, ability of
absorbing microwave are reviewed. Examples of application for the foam materials, such as catalysis,
filtration, biological and so on are introduced. In addition, application of SIC foams as column internals
for chemical industry is presented. Higher demand for Sic foams requires not only integration and
renovation of current technologies, but also development of their potential advantages
