ABRASIVE TECHNICAL INFORMATIONMC Finishing
SILICON CARBIDE (SIC) or carborundom is a naturally occurring but mainly man made abrasive produced by heating or fusing silicon and carbon in vast outdoor facilities. Silicon carbide (S/C) has a sharp slivery shape and is more friable than aluminum oxide. S/C hardness is 9.5 on the Mohs scale. S/C is widely used for

Silicon Carbide SiC Material Properties
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.
