Silicon Carbide was accidentally invented by Edward G. Acheson in 1891 while trying to produce artificial diamonds. The mixture of silica fine sand and fine coke is built around a carbon dioxide conductor within a brick electric resistance type heater. Electric current is exceeded through the furnace to bring about the substance reaction between carbon in coke and the silicon in sand to form the compound SiC and carbon monoxide gas. By 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 crystals, the lesser the purity. Some natural carbide is found in Arizona in Canyon Diablo meteorite. The majority of the silicon carbide sold in the planet 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. That was first put to use as an abrasive and later used in electronic applications. This was also used as a detector in radios in 20th century. In 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 opposition, and fantastic chemical inertness. Due to its properties it is widely used in suction box includes, seals, bearings, ball valve parts silicon carbide, hot gas circulation liners, heat exchangers, semiconductor process equipment and repaired and moving turbine components.
In today’s world it is usually used in abrasives such as grinding, water-jet cutting, sandblasting etc. Allergens of the silicon carbide are being used in sandpaper. It is also found in various automobile parts such as brake disks because of to its resistance from extreme temperatures. The compound is also used in the mirror of the massive telescope because of its rigidity and hardness and thermal conductivity. It is also used to melt glass and non-ferrous metals, production of ceramics, float glass production, steel production, as driver support, graphene production and so on.---
