Application Of Silicon Carbide Ceramics
- Apr 04, 2018 -

Due to the high hardness, high corrosion resistance, and high high temperature strength of silicon carbide ceramics, silicon carbide ceramics have been widely used. There are mainly the following aspects:

Sealing ring: Silicon carbide ceramics have good chemical resistance, high strength, high hardness, good wear resistance, low friction coefficient, and high temperature resistance. Therefore, it is an ideal material for manufacturing seal rings. When it is paired with a graphite material, the friction coefficient is smaller than that of alumina ceramics and hard alloys. Therefore, it can be used for high PV values, especially in working conditions where strong acids and alkalis are transported. The SIC-1 silicon carbide pressureless sintered products produced by our company have the characteristics of high density, high hardness, large production volume, and the ability to produce complex shaped products, and are suitable for use in high performance seals, especially high PV values and Resistant to strong acids and alkalis. The SIC-3 silicon carbide ceramic products produced by our company are graphite-containing silicon carbide materials. Due to the large amount of dispersed fine graphite particles in the silicon carbide matrix, when used in combination with other materials, the friction coefficient is very small and has good self-lubricating properties. It is especially suitable for producing hermetic seals or seals with dry friction conditions. Used to improve seal life and reliability.

Grinding media (grinding media): Silicon carbide ceramics are widely used in wear-resistant mechanical parts because of their high hardness, especially grinding media (milled media) in ball mills. The grinding media used in the ball mill has an important influence on the grinding efficiency. The basic requirements are high hardness and good toughness to ensure high grinding efficiency and low doping requirements. The SIC-1 type silicon carbide ceramic grinding media produced by our company is suitable for use in ordinary ball mills. It has the features of high hardness, high strength, and moderate price. The SIC-2 silicon carbide ceramic mill is suitable for use in vibrating ball mills and agitating ball mills due to its high strength and good toughness. Reasonably choosing grinding media ensures that you get higher grinding efficiency and minimal doping at the lowest cost.
