Study of formation of silicon carbide in the Acheson process

The century old Acheson process is still used for the mass production of silicon carbide. A heat resistance furnace is used in the Acheson process which uses sand and petroleum coke as major raw materials. It is a highly energy intensive process. No mass transfer model is available for this process.

Production of a high value ceramic material: Silicon carbide

Silicon carbide is often referred to as “carborundum”: this vernacular term commemorates a word coined by Edward G. Acheson in 1892 to describe crystals that he made in an experiment which had the real goal of making a diamond-like crystal from carbon and alundum. Using a primitive furnace of his own design, he in fact made SiC.

How silicon is made - material, making, history, used

When silicon is heated it reacts with the halogens (fluorine, chlorine, bromine, and iodine) to form halides. It reacts with certain metals to form silicides and when heated in an electric furnace with carbon, a wear resistant ceramic called silicon carbide is produced. Hydrofluoric acid is the only acid that affects silicon.
