Compared to silicon or gallium arsenide, the Silicon carbide (SiC) is a rather young base material in the semiconductor industry but its origins date back to the end of the 19th century. In 1891, Edward Acheson developed a method for producing crystalline SiC as an
Silicon Carbide is derived from powder or grain, produced from carbon reduction of silica. It is produced as either fine powder or a large bonded mass, which is then crushed. To purify (remove silica) it is washed with hydrofluoric acid.
For special appliions, silicon carbide is produced by a nuer of advanced processes. Reaction-bonded silicon carbide is produced by mixing SiC powder with powdered carbon and a plasticizer, forming the mixture into the desired shape, burning off the plasticizer, and then infusing the fired object with gaseous or molten silicon, which reacts with the carbon to form additional SiC.
Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace. The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring.
Silicon Carbide Powder: The ability of Silicon Carbide to withstand very high temperatures without breaking or distorting is used in the manufacture of ceramic brake discs for sports cars. It is also used in bulletproof vests as an armor material and as a seal ring material for pump shaft sealing where it frequently runs at high speed in contact with a similar silicon carbide seal.

The U.S. imported crude silicon carbide from eight countries and imported ground and refined silicon carbide from 21 countries. Imports of crude silicon carbide increased by 18% during the year to 163,000 tons valued at $69.3 million.Imports of silicon carbide in ground or refined form increased 49% to 45,300 tons valued at $49.9 million.
During World War II, silicon carbide was used as a heating element; however, it was difficult to obtain high density sintered silicon carbide bodies. In 1974, S. Prochazka reported that the addition of small amounts of boron compounds and carbide were effective in the sintering process to obtain high density.
