Silicon carbide (SiC) has very similar properties to diamond - it is one of the lightest, hardest and strongest technical ceramic materials, with excellent thermal conductivity, acid resistance and low thermal expansion. When physical wear is an important consideration, silicon carbide is an excellent material because it has good corrosion and wear resistance, making it useful in a variety of applications, such as nozzles, shot peening nozzles and cyclone components.

Silicon carbide ceramics (SiC) is a kind of advanced ceramic material containing silicon and carbon. It exists in nature as an extremely rare mineral called moissanite. Synthetic SiC powders have been produced in large quantities since 1893 for use as abrasives. Silicon carbide particles can be bonded together by sintering to form very hard ceramics.

With the rapid development of modern national defense, nuclear energy and aerospace technology, automobile industry and ocean engineering, the requirements for materials are getting higher and higher. High performance structural ceramic materials are widely used in daily life. Silicon carbide ceramic materials have high high temperature strength, good wear resistance, small thermal expansion coefficient, high hardness, thermal shock resistance, chemical corrosion resistance and many other excellent properties, so widely used in automotive, machinery, chemical industry and other industries. Environmental protection, space technology, information electronics, energy and other fields. Silicon carbide has become an irreplaceable structural ceramic and has excellent properties in many industrial fields. For example, silicon carbide ceramics in the petrochemical industry has been widely used as corrosion resistant containers and pipelines, in the machinery industry has also been successfully used in a variety of bearings, tools and mechanical seals.
