silicon carbide lapping

water polishing and lapping

Silicon carbide (SiC) is a rare naturally occurring mineral known as moissanite. This substance has been synthetically produced for industrial use since the late 19th century. It was first used as an abrasive applicant, an early LED, a gemstone stimulant, and a protective coating. However, breakthrough research has discovered that this substance works as an excellent semiconductor.

Silicon carbide is a wide bandgap semiconductor that can be used in processes or devices that require high levels of temperature, power, and voltage. Such applications are predicted to modernize our technology in the next few decades. Demands for innovation will come from high speed rail, solar and wind energy, automotive, medical, and other industries. Silicon carbide will help semiconductor and inverter end-users to innovate further than previously thought possible. Silicon carbide is proposed to revolutionize energy and civilization by the mid-twenty-first century.
