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.

High-Temperature Electronic Switching | Science
In electronic circuitry, the band gap of a semi-conductor helps to provide the barrier that keeps charge carriers from flowing until a voltage is applied that switches the device. As temperatures rise, the carriers acquire enough thermal energy to overcome the band gap, causing the device to leak current even when they are turned off. The higher band gap of silicon carbide (SiC) makes it an
