Material of the month – silicon carbide | IOM3
Sitting at an impressive 9–9.5 on the Mohs hardness scale, silicon carbide proved to be a much more powerful abrasive than those based on emery, corundum and garnet that came before. Alongside synthetic alumina, silicon carbide abrasives reigned supreme until 1955, when Howard Tracy Hall at the General Electric Company (GE) finally succeeded in producing synthetic diamonds.

All About Abrasives | American Machinist
Silicon Carbide Silicon carbide is a hard, sharp abrasive that has exceptional strength. However, due to its brittleness, it breaks down faster than aluminum oxide under heavy loads. Black silicon carbide is a semifriable, medium-density abrasive.
Black silicon carbide is harder than aluminum oxide, and 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.
