Black silicon carbide (Carborundum) is generally used for the abrasive wheel, slurry, refractory and ceramic industries. Silicon Carbide is special in the way it breaks down. As it breaks down into smaller particles, the media will expose new, sharp edges. Therefore, black silicon carbide can be best used over and over, such as in a rock tuler.

15.07.2019· If the abrasive is softer than the carbide the abrasive is not able to abrade the carbide. Notably, aluminum oxide (Alumina), the most common abrasive, is softer than VC, NbC, and WC. However, if the abrasive size is larger than the carbide size then the abrasive is able to pull out the steel and the carbides together so that the carbide hardness isn’t as important.

Each abrasive grain can be regarded as an undefined cutting edge; thus, a multiple cutting edge tool is formed through the surface abrasive grains interconnected by the matrix. In grinding tools with ceramic bond the abrasive particles like diamond, CBN, corundum (α-Al 2 O 3 ) or SiC are interconnected by a vitreous or a glass-ceramic matrix and thus silie bonded.
