Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”

Silicon carbide semiconductors are used in electric cars, solar power, and service power supplies used to store vast amounts of data, light emitting diodes, and sensor appliions. These markets at present are coined over 1 billion USD annual revenue, and they are growing 40-50% year over year.
Black silicon carbide (SiC) is a semi-friable abrasive often used for general abrasive appliions in bonded abrasive tools, lapping, polishing, tock tuling, glass etching and frosting. It is extremely resistant to wear, chemicals, and corrosion, making it excellent for sandblasting nozzles, furnace components, engine components, high tech ceramics, etc. It is also an
Silicon Carbide semiconductors are compound semiconductors developed by the composition of carbon and silicon. Silicon Carbide offers numerous advantages over silicon, which include enabling a wider range of p- and n-type control required for device construction, 3x the band gap, and 10x the breakdown electric field strength.

Using GaN on silicon carbide substrates, Eudyna successfully brought into production transistors designed for the RF market 3. The HEMT structure was based on the phenomenon first described in 1975 by T. Mimura et al 4 and in 1994 by M. A. Khan et al 5 , which demonstrated unusually high electron mobility near the interface between an AlGaN and GaN heterostructure interface.

Silicon carbide, often referred to by its chemical formula, SiC, is a synthetically produced crystalline compound consisting of silicon and carbon. Due to its exceptional abrasive properties, SiC was the first synthetic abrasive to be produced and has been in use since the late 19th century, in appliions ranging from sandpaper to grinding wheels and cutting tools.
