Silicon Carbide was accidentally invented by Edward G. Acheson in 1891 while trying to produce artificial diamonds. A new mixture of silica crushed stone and fine coke is built around a co2 conductor within a stone electric resistance type furnace. Electric current is exceeded through the furnace to bring about the chemical reaction between the carbon in coke and the si in sand to form the compound SiC and carbon monoxide gas. Towards the end you have green and black crystal like components which are later crushed and ground into various size as per use. The darker the deposits, the lesser the chastity. Some natural carbide is found in Arizona in Canyon Diablo meteorite. Almost all of the silicon carbide sold in the world is synthetic.

Acheson patented the method of making silicon carbide in 1893. Silicon carbide is also called carborundum because Acheson was trying to dissolve carbon in smelted corundum (alumina) when this material was discovered. This was first put to use as an abrasive and later utilized in electronic applications. That was also used as a detector in radios in 20th century. Inside 1907 LED was first produced by Henry Joseph Round by applying high voltage to silicon carbide crystals.
This chemical has low density, high durability, low thermal expansion, high thermal conductivity, high firmness, excellent thermal shock level of resistance, and fantastic chemical inertness. Due to its properties it is widely used in suction box includes, seals, bearings, ball control device parts, hot gas flow liners silicon carbide, heat exchangers, semiconductor process equipment and fixed and moving turbine components.

In today's world it is commonly used in abrasives such as grinding, water-jet cutting, sandblasting etc. Contaminants of the silicon carbide are being used in sandpaper. This is also found in various automobile parts such as brake disks due to its resistance to extreme temperatures. The compound is also used in the mirror of the massive telescope because of their rigidity and hardness and thermal conductivity. It is also used to melt glass and non-ferrous metals, production of ceramics, float glass manufacturing, steel production, as driver support, graphene production and so on.
