What is silicon carbide?


The properties of silicon carbide ceramic are very similar to diamonds - it is one of the lightest, hardest and strongest technical ceramic materials, with excellent thermal conductivity, acid resistance and low thermal expansibility. When physical wear is an important factor, silicon carbide is a good material because it has good corrosion resistance and abrasion resistance, which can be used in various applications, such as nozzle, shotgun nozzle and cyclone component.

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 mosamite. Synthetic SiC powders have been mass-produced since 1893 for use as abrasives. Silicon carbide particles can be sintered together 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 coefficient of thermal expansion, high hardness, thermal shock resistance, chemical corrosion resistance and many other excellent characteristics, so it is widely used in automobile, machinery, chemical industry and other industries. , environmental protection, space technology, information electronics, energy and other fields. Silicon carbide has become an irreplaceable structural ceramic with excellent properties in many industrial fields. For example, silicon carbide ceramics in the petrochemical industry has been widely used as corrosion resistant vessels and pipes, in the machinery industry has also been successfully used in a variety of bearings, tools and mechanical seals. Beyond that, silicon carbide is considered one of the most promising candidates for future production of gas turbines, rocket nozzles and engine components in the aerospace and automotive industries.
