Features and application of Reaction Bonded Silicon Carbide

Reaction bonded silicon carbide is a composite material made up of silicon carbide particles bound together by a ceramic matrix. Reaction bonded silicon carbide is a multi-phased material that generally contains 7-15% silicon metal and a small amount of unreacted carbon, with the remainder being SiC. reaction bonded sic is the refractory grade silicon carbide, meaning that it has a large melting point and can cope with temperatures in excess of 200 C without major deformation or deterioration. The manufacturing process of this kind of silicon carbide involves infiltrating molten silicon into the porous carbon material which has been packed in such a way as to form the desired part. Silicon carbide is formed when carbon and molten silicon are mixed.

The production process depends on the desired geometry, configuration and relevant tolerances of the finished product. Reaction Bonded Silicon Carbide has high strength, excellent thermal and chemical resistance, and can be produced in a variety of shapes and sizes. RB SiC is often used in pumps, mechanical seals, bearings, pipe linings, flow control chokes and larger wear components in mining and other sectors when high wear resistance and dimensional stability are required.

Features of Reaction-Bound Silicon Carbide
