Silicon Carbide (SiC): History and Appliions | DigiKey

One of the primary uses of silicon carbide is high performance "ceramic" brake discs. The silicon coines with the graphite in the composite to become carbon-fiber-reinforced silicon carbide (C/SiC). These brake discs are used on some sports cars, supercars, and other performance vehicles. Another automotive use of SiC is as an oil additive.
