In the silicon carbon system, the only compound species that exists in the solid state is silicon carbide, SIC (Elliott, 1966). It does, however, exist in bth beta and alpha modifiions. The beta, or cubic, modifiion crystallizes in the zinc- blende or sphalerite (diamond cubic) form.

Three Methods Of Sintering Silicon Carbide Ceramics

Three Methods Of Sintering Silicon Carbide Ceramics. 1) No pressure sintering. In 1974, GE company in the United States attempted to add a small amount of B and C to high-purity beta-SIC fine powder, and successfully obtained high-density SiC ceramics at 2020°C by using the pressure-free sintering process. The process has become the most important

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.
