Navarro SiC - Silicon Carbide

Silicon carbide (SiC) is a synthetic material with an exceptional hardness, highly wear resistance and chemically inert to alkalis and acids. It was discovered in 1893 by Henri Moissani (France) while examining rock samples from a meteorite crater loed in Devil''s Canyon (Arizona, United States).

Silicon Carbide SiC Material Properties

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. 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.
