Classification of silicon carbide products

Silicon carbide raw material products can be divided into many categories, which are divided into different types according to different use environments. Generally, it is used more mechanically. For example, when used on mechanical seals, it can be called silicon carbide seal ring, which can be divided into static ring, moving ring, flat ring, etc. We can also produce various shapes of silicon carbide products according to the special requirements of customers, such as silicon carbide special-shaped parts, silicon carbide plates, silicon carbide rings, etc.

Silicon carbide ceramics, one of the products of silicon carbide, have the characteristics of high hardness, high corrosion resistance and high temperature strength, which makes silicon carbide ceramics widely used.

Application in sealing ring: silicon carbide ceramic has good chemical corrosion resistance, high strength, high hardness, good wear resistance, small friction coefficient and high temperature resistance, so it is an ideal material for manufacturing sealing ring. When combined with graphite materials, its friction coefficient is smaller than that of alumina ceramics and cemented carbide, so it can be used in high PV value, especially in the working condition of conveying strong acid and alkali. Sic-1 silicon carbide atmospheric pressure sintered products produced by our company have the characteristics of high density, high hardness, large production batch and can produce products with complex shapes. They are suitable for high-performance seals, especially under the working conditions of high PV value and resistance to strong acid and alkali. The sic-3 silicon carbide ceramic products produced by our company are silicon carbide materials containing graphite. Because there are a large number of dispersed fine graphite particles in the silicon carbide matrix, when paired with other materials, its friction coefficient is very small and has good self-lubricating performance. It is especially suitable for making gas seals or seals with dry friction conditions, so as to improve the service life and working reliability of seals.
