Silicon Carbide Ceramic Material Supplier

Silicon Carbide. SiC exists in nature as the extremely rare mineral called moissanite, while most of this material is synthesized in factories. As SiC is extremely hard, It has been mass produced as abrasive since late 19th century. Silicon carbide powder has a black color when the purity is low and products with purity higher than 90% is green.

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 SiC Material Properties - Accuratus

Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800 C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities.
