Silicon Carbide (SiC) | Morgan Technical Ceramics

Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles.

SiC Production Process | Washington Mills

Silicon carbide crude is produced by mixing silica (SiO2) with carbon (C) in an electric resistance furnace at temperatures around 2,500 C. The chemical reaction in the SiC process may be represented by the formula: SiO2 + 3C SiC + 2CO. Washington Mills employs two different manufacturing methods for producing SiC crude: the traditional Acheson
