Silicon CarbideStructure Properties and Uses of SiC
Silicon carbide also commonly known as Carborundum is a compound of silicon and carbon. Silicon carbide is a semiconductor material as an emerging material for applications in semiconductor devices. Silicon carbide was discovered by Pennsylvanian Edward Acheson in 1891. It is one of the most important industrial ceramic materials.
