Carbure de silicium — Wikipédia
Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique ultraréfractaire 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.
