silicon carbide production process

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.

Silicon Carbide - Production | Technology Trends

Pure silicon carbide can be made by the so-called Lely process, in which SiC powder is sublimated in argon atmosphere at 2500 °C and redeposited into flake-like single crystals, sized up to 2×2 cm2, at a slightly colder substrate. This process yields high-quality single crystals, mostly of 6H-SiC phase (because of high growth temperature).
