Silicon Carbide Powder Appliion: Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years.
Typically, Silicon Carbide is produced using the Acheson process which involves heating silica sand and carbon to high temperatures in an Acheson graphite resistance furnace. It can be formed as a fine powder or a bonded mass that must be crushed and milled before it can be used as a powder feedstock.
SiC powders can be produced through industrial and laboratory methods. Using industrial methods, SiC powders are manufactured using the Acheson process through the carbothermic reduction of silicon dioxide (SiO 2) using carbon powder at extremely high temperatures (2200–2400 C) with a heating time of 30 h [4,9,11,14].].
Silicon carbide (SiC) is a compound of silicon and carbon with a chemical formula of SiC. The simplest manufacturing process for producing silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F).
