Sintering and application of the reaction bonded silicon carbide
- Dec 06, 2018 -

The reaction bonded silicon carbide is a process in which a raw material molded body is subjected to a chemical reaction at a high temperature of 1,720 ° C, and a liquid and gas phase are chemically reacted with each other, and densification and synthesis of a predetermined component are carried out to obtain a predetermined sintered body. As a high-tech industrial ceramic material, the reaction bonded silicon carbide has high temperature strength, strong oxidation resistance, strong acid and alkali corrosion resistance, good thermal stability, high thermal conductivity, and hardness second only to diamond.


The reaction bonded silicon carbide has been processed into a silicon carbide nozzle burner sleeve, a silicon carbide beam roller, a silicon carbide cold air tube, a silicon carbide radiant tube, a silicon carbide preheating tube air guiding sleeve, and a silicon carbide blasting nozzle. Silicon carbide desulfurization nozzle, silicon carbide wear-resistant lining and other high temperature resistant, wear-resistant, corrosion-resistant products. It is widely used in electric power, steel, ceramics, high temperature furnace, mining, coal, alumina, petroleum, chemical, environmental wet desulfurization, machinery manufacturing and other industries.

The silicon carbide torch nozzle has high temperature strength, oxidation resistance, wear resistance, rapid cooling resistance, long-term high temperature use, no breakage, no deformation, and can effectively control the temperature balance in the furnace. It is widely used in daily-use porcelain, sanitary porcelain, building ceramics and other high-temperature kiln such as kiln fire-blasting kiln
