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 tumbler.

Black Silicon Carbide grit (SiC) is an extremely hard (Mohs 9.1 / 2550 Knoop) man-made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3). Silicon Carbide Specifications

Silicon carbide shows up in two diverse glasslike structures: hexagonal α-silicon carbide is the primary item, while cubic β-silicon carbide is shaped at lower temperatures. Silicon carbide grit (SiC) is made in an opposition curve heater charged with a combination of around 60% silica sand and 40 percent finely ground petrol coke.

In a sentence: Silicon carbide is a hard, dark gray, chemically-stable ceramic that, in recent years, has become the workhorse ceramic armor material in high-end and military body armor systems. Silicon carbide was accidentally discovered in 1891 by by Edward Goodrich Acheson, formerly an assistant to Thomas Edison, during experiments on the synthesis of diamonds in electric arc furnaces.

In comparison, silicon carbide grit has a Mohs hardness level of 9+, and, as such, it is a much more effective abrasive. Sand can be used as an abrasive for tumbling agate or jasper, however, it will take a lot more time. Additionally, you would need around twice the amount of sand as a substitute grit, than if you would use silicon carbide grit.

Black Silicon Carbide is produced in an electric resistance type furnace with petroleum coke and quartz sand as its primary raw materials at high temperatures. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is sharp and has electrical heat conductivity to some degree. Ideal for a wide variety of applications, including ...
