Silicon Carbide was accidentally invented by Edward G. Acheson in 1891 while trying to produce artificial diamonds. A mixture of silica crushed stone and fine coke is built around a carbon conductor within a brick electric resistance type heater. Electric current is exceeded through the furnace to bring about the chemical substance reaction between 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 smashed and ground into various size as per use. The darker the uric acid, the lesser the chastity. Some natural carbide is found in Arizona in Canyon Diablo meteorite. Most 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 molten corundum (alumina) when this material was discovered. It was first put to use as an abrasive and later used in electronic applications. It 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 silicon carbide, low thermal expansion, high thermal conductivity, high solidity, excellent thermal shock level of resistance, and fantastic chemical inertness. Due to its properties it is widely used in suction box covers, seals, bearings, ball valve parts, hot gas circulation liners, heat exchangers, semiconductor process equipment and fixed and moving turbine components.
In today's world it is often used in abrasives such as grinding, water-jet cutting, sandblasting etc. Contaminants of the silicon carbide are being used in sandpaper. It is also found in various automobile parts such as brake disks credited to its resistance to extreme temperatures. The compound is also used in the mirror of the astronomical telescope because of its rigidity and hardness and thermal conductivity. It is usually used to melt glass and non-ferrous metals, production of ceramics, float glass manufacturing, steel production, as prompt support, graphene production and so forth.
