Silicon Carbide Powder Appliion SiC fibers are produced via the pyrolysis of organosilicon polymers, such as polycarbosilane, and are commercially available. Briefly, the process consists of meltspinning the polycarbosilane at approximately 300°C, unfusing with thermal oxidation at 110200°C, and baking at °C under a flow of inert gas.

Penn United Carbide is the premier manufacturer of tungsten carbide and silicon carbide components engineered for today's most rigorous appliions. These appliions range from erosion and corrosion resistance in the Oil Gas industry to high impact strength and toughness in the tool and die marketplace.
Pure silicon carbide can be made by the socalled Lely process, in which SiC powder is sublimated in argon atmosphere at 2500 °C and redeposited into flakelike single crystals, sized up to 2×2 cm2, at a slightly colder substrate. This process yields highquality single crystals, mostly of 6HSiC phase (because of high growth temperature).
