Black silicon carbide is made from quartz sand, petroleum coke, or anthracite, and produced in a resistance furnace at high temperature. Its hardness is between corundum and diamond. It has higher strength than corundum, and is brittle but sharp.

It has some electrical and thermal conductivity. It is used to make abrasives for processing low tensile strength metals and non-metals, such as gray cast iron, non-ferrous metals, stone, leather, and rubber.

It is also widely used in refractory materials and as a metallurgical additive.
