Reaction Bonded Silicon Carbide

Reaction bonded silicon carbide compositions have been designed for optimum strength and corrosion resistance. The benefits of using reaction bonded silicon carbide include: exceptional wear resistance, long life due to its excellent resistance to oxidation, excellent thermal shock resistance, and large or small complex shape capabilities.

Nitride Bonded Silicon Carbide

Silicon nitride bonded silicon carbide is designed for exceptional wear resistance. It can be formed into very intricate shapes due to its castable characteristics and also has desirable refractory and chemical properties. Its primary use will be where the highest wear resistance is needed or where shape is too intricate to make in other mixtures. Double fired versions that have less open porosity and improved oxidation resistance are also available.

Sintered Silicon Carbide

Sintered alpha silicon carbide is produced by sintering ultra-pure submicron powder. This powder is mixed with non-oxide sintering aids, then formed into complex shapes by a variety of methods and consolidated by sintering at temperature above 3632°F.

The sintering process results in a single-phase fine-grained silicon carbide that is very pure and uniform, with virtually no porosity enabling the materials to withstand corrosive environments, abrasive environments, and environments operating under high temperature (2552°F). These properties make sintered alpha silicon carbide ideal for applications such as chemical and slurry pump seals and bearings, nozzles, pump and valve trim, paper and textile components, and more.
