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.

The superiority of these gallium oxide devices stems from the material’s approximately 5–electron-volt bandgap—way higher than that of gallium nitride (about 3.4 eV) or silicon carbide
2018/9/25· While the silicon carbide igniter was engineered to last the full life of a furnace, due to typical issues that lead to short cycling, typical igniter life is in the eight to twelve years range. I n the late 1990’s and early 2000’s , some manufacturers started using Silicon Nitride igniter technology, with Lennox and Trane being early adopters.
Worth knowing: Properties of Silicon Carbide (SSiC / SiSiC) Low density (3.07 to 3.15 g/cm 3) High hardness (HV10 ≥ 22 GPa) High Young’s modulus (380 to 430 MPa) High thermal conductivity (120 to 200 W/mK) Low coefficient of linear expansion (3.6 to 4.1x10-6 /K at 20 to 400 C)
In 2016, the NATO Science for Peace and Security Programme funded research project ”Engineering Silicon Carbide for Border and Port Security” — E-SiCure was launched, its objective being the development of radiation-hard silicon carbide (SiC) based detectors
