2. Is silicon carbide naturally abrasive? Since its initial discovery in 1891, SiC has been produced in powder form and used as a synthetic abrasive material.This is due to its high level of hardness, ranking 9 on the Mohs scale, which outclasses most known materials, only to be surpassed by a handful of others, such as boron, boron nitride, and diamond.
