Metallurgy grade silicon carbide is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F). Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material. The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1,500 °C (2,730 °F).

Black silicon carbide particles can be bonded together by sintering to form a very hard ceramic that is widely used in applications that require high durability, such as automotive brakes, automotive clutches and ceramic plates in bulletproof vests. Metallurgy grade silicon carbide is used in semiconductor electronic devices that operate at high temperatures or voltages, or both. Large single crystals of foundry grade silicon carbide can be grown by the Rayleigh method; they can be cut into gemstones called synthetic moissanite. Green silicon carbide with a high surface area can be produced from SiO2 contained in plant material.
