Carbure de silicium — Wikipédia

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.

What Is The Difference Between Alpha SiC And Beta SiC …

The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.
