Product Description

Product Description

Silicon carbide (SiC), also known as carborundum, is a hard chemical compound containing silicon and carbon. They are widely used for abrasives, refractory, metallurgy, and SiC wafer, etc. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests.
