Silicon carbide has been used extensively as an abrasive, but only in the last 25 years has its potential as a semiconductor been exploited. The rationale for SiC semiconductor devices is their high temperature performance. Rectifiers, field effect transistors, charged particle detectors, and other devices operate efficiently at temperatures about 800 K.
