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.

Basic Parameters of Silicon Carbide (SiC)

Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende); 2H-SiC; 4H-SiC; 6H-SiC (hexagonal unit cell, wurtzile ); 15R-SiC (rhoohedral unit cell).Other polylypes with rhornbohedral unit cell: 21R-SiC 24R-SiC, 27R-SiC etc.

strength and a thermal conductivity of at least 200 W m 1 K 1 has to be developed. Due to its high thermal conductivity of about 400 W m 1 K 1, copper is an excellent heat sink material. The problem is its low creep resistance and strength under thermal loads and neutron irradiation. The aim of this work is to improve the high temperature
