Silicon Carbide Foam

Silicon carbide foam is a kind of special porous ceramics with a uniform three-dimensional network structure. It has uniform pore distribution, high porosity, small relative density, large specific surface area, selective permeability to liquid and gas media, as well as good energy absorption and pressure resistance and excellent thermal, electrical, magnetic, optical, chemical functions. Silicon carbide foam has been widely used in metallurgy, chemical industry, energy, electronics, transportation, machinery, national defense, environmental protection, biology, and other fields.

Special Properties

• Thermal Conductivity—Silicon carbide foam has high thermal conductivity. Because of the high surface area of silicon carbide foam, heat transfer to/from fluids flowing through the foam is greatly accelerated.
• Electrical Conductivity—Silicon carbide foam can be used in electrochemical processes that require low electrical and fluid flow resistance. This is in stark contrast to most ceramics, which do not conduct electricity.
• Corrosion resistance—Silicon carbide foam has high resistance to oxidant and acid corrosion.

Applications

As its excellent features, silicon carbide foam shows Silicon carbide foam ceramics draws increasing interests in many application fields. The typical applications are as follows:

• Catalyst

Due to its high porosity, thermal conductivity, mechanical strength, oxidation resistance, corrosion resistance and its special network structure, silicon carbide foam is a new generation of the catalyst carrier that can replace the traditional catalyst carrier, such as silica, alumina ceramics, and activated carbon.

• Filter

With the characteristics of large porosity, good air permeability, large specific surface area, and high thermal shock resistance, silicon carbide foam has been successfully applied in automobile exhaust gas purifiers. Silicon carbide foam is also expected to obtain significant economic and social benefits in the application of metal solution filtration in the casting industry.

• Chemical Industry

Silicon carbide foam can be used as structure filler and column tray, it can be used in several chemical equipment, such as steam generator, high pressure adiabatic burner, radiation burner, to greatly improve the heat transfer coefficient and strengthen the combustion process.

• Other Fields

Due to its unique network structure, silicon carbide foam can be used in sound absorption and noise reduction material. Because of its excellent corrosion resistance and the ability to be heated by electricity, silicon carbide foam can be used in heating of corrosive fluids in construction departments and semiconductor fields, and it can also be used to make all kinds of heat exchangers. Silicon carbide foam has good biocompatibility and pore size controllability, which can be used for complex shape and long length bearing bone defect repair
