Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON
Garnet wears out the fastest but produces the smoothest surface. Silicon carbide is ideal for sanding harder materials such as metals and plastic. Finally, ceramic, the most expensive and roughest grit, is used for shaping wood.
Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique réfractaire ultradure semiconductrice synthétique, qu''on peut trouver dans la nature sous la forme d''un minéral très rare, la moissanite.Grâce au procédé Acheson, depuis la fin du XIX e siècle, on sait produire industriellement de la poudre de carbure de silicium, qui servit d''abord comme abrasif.

Halvledere er materialer, der har en elektrisk ledningsevne, der ligger mellem de ledende materialer og de isolerende. Der er ikke nogen skarp definition af, hvad en halvleder er, men det er typisk materialer med en resistivitet, der ligger i området fra ca. 10-5 til ca. 107 Ω · m. Der er følgende kendetegn ved et rent halvledermateriale
