Silicon carbide (SiC) is an extremely hard synthetic material with multiple industrial uses. As a non oxide ceramic, SiC boasts unique properties including high melting point, thermal conductivity and corrosion resistance – three properties essential to industrial processes. Black SiC is used in abrasives and as moissanite; an attractive synthetic gemstone.
