Is there a requirement for the selection of raw materials for Reaction Bonded Silicon Carbide
- Jan 06, 2019 -

The Reaction Bonded Silicon Carbide has a harsh environment in use, such as corrosion of sulfurous acid and sulfuric acid, wear and corrosion caused by calcium sulfite, calcium sulfate and calcium carbonate particles, which seriously affects the performance and use of the Reaction Bonded Silicon Carbide. life. Therefore, the raw materials for the Reaction Bonded Silicon Carbide are usually selected to be corrosion-resistant and wear-resistant silicon carbide.


The Reaction Bonded Silicon Carbide has the characteristics of high hardness, high corrosion resistance and high high-temperature strength, which makes the Reaction Bonded Silicon Carbide widely used. Applied on the sealing ring, the Reaction Bonded Silicon Carbide has good chemical resistance, high strength, high hardness, good wear resistance, small friction coefficient and high temperature resistance, and is therefore an ideal material for manufacturing the sealing ring.


The Reaction Bonded Silicon Carbide is a graphite-containing silicon carbide material. Because it contains a large amount of fine and 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, and is particularly suitable. It is used in the manufacture of seals with airtight or dry friction conditions, so that the service life and reliability of the seals are
