Silicon Carbide SiC Material PropertiesAccuratus
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.
