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.
