Silicon carbide sic gasket ring

Silicon carbide sealing rings are the most widely used wear resistant materials as mechanical seals. It has strong chemical resistance, high mechanical strength, good wear resistance, high temperature resistance, and good self-lubricating properties. It is widely used in petroleum, chemical, aerospace, automotive and other fields. It is grouped with carbon graphite and has the lowest friction coefficient, so it can be used as a high-parameter mechanical seal.

1.Introduction of Silicon Carbide:

  Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with a chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite.

  Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in applications requiring high endurance, such as car brakes and ceramic plates in bulletproof vests.

  Electronic applications of silicon carbide as light emitting diode and detector in early radios have been demonstrated around 1907, and nowadays SiC is widely used in high-temperature semiconductor electronics.

  Large single crystals of silicon carbide can be grown by the Lely method; they can be cut into gems known as "synthetic moissanite". Silicon carbide with high surface area can be produced from SiO2 contained in plant material.
