Silicon carbide (SiC) is an ultra-hard non-oxide ceramic with distinct properties and applications, first discovered in 1891 by American inventor Edward G. Acheson while trying to produce artificial diamonds. SiC is typically an insulator in its pure state but can exhibit semi-conductivity through controlled doping. A wide bandgap material like SiC can move electrical energy more efficiently than traditional semiconductors. Origin Silicon carbide (SiC) is a hard, brittle compound of carbon and silicon with the chemical formula SiC. This material occurs naturally as the mineral moissanite but has been mass produced as an abrasive since 1893. Grains of this material can be fused together using sintering to produce very hard …
