Silicon Carbide Definition

Silicon carbide (SiC) is a hard, synthetically produced crystalline compound widely used as an abrasive and wear-resistant material, in refractories and ceramics applications, as well as being the semiconductor substrate for light emitting diodes (LED). EFM semiconductors also outshone traditional silicon semiconductors in high-voltage environments like those found in electric vehicle (EV) power devices, providing superior performance by minimizing losses in voltage and current as well as shrinking and lightening essential battery management components while decreasing size and weight....
