Silicon Carbide (SiC) is a wide bandgap material. Wide bandgap technologies have many advantages compared to Silicon. Operating temperatures are higher, heat dissipation is improved and switching and conduction losses are lower. However, wide bandgap materials are more difficult to mass produce compared to silicon based ones.

Nov 03, 2007· Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
Silicon Carbide wafers are disks with a thickness of 350 micrometes (approximately 1/3 millimeter) and an average diameter of 150 mm. These wafers must meet demanding specifiions, set by our customers. Our closely monitored high tech manufacturing processes guarantee the utmost quality throughout all steps of the process.
Silicon carbide is a fast-cutting abrasive commonly used on non-ferrous metals and in low-pressure appliions. Crimped bristle discs are more durable than straight discs. They are commonly used where the impact of a knotted brush would alter the workpiece. Drive arbors are used for securely mounting disc brushes in milling or CNC machines.
