PureSiC CVD Silicon Carbide | CoorsTek

Chemical vapor deposition (CVD) silicon carbide resists corrosion in extreme environments while maintaining the high strength and excellent wear properties of silicon carbide. This capability, coined with the exceptional purity of 99.9995%, is helping make the ultra-clean manufacturing used in semiconductor production run faster and more efficiently.

Grades - General Carbide

Tungsten carbide (WC), also referred to as cemented carbide, is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace.

Silicon carbide - Wikipedia

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions

Silicon carbide formation by annealing C films on silicon

Silicon carbide films were grown on ~100! silicon substrates by deposition of 200-nm-thick C60 films, followed by annealing. The predeposited C60 is progressively destroyed by annealing, and carbon reacts with silicon to produce SiC. The reaction starts at the interface and continues by diffusion of silicon through the already formed SiC.

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.
