Overview of Silicon Carbide
Silicon carbide is used as a semiconductor replacement for silicon in many high-powered appliions because of its high temperature capabilities, high frequency abilities, and good switching speed. However, SiC also has found use in ballistic armoring in the form of fiber reinforcers or wet/dry-milled silicon carbide coined with aluminum nitride.
