Silicon Carbide (SiC): Part One :: Total Materia Article

Silicon Carbide Production . Silicon Carbide is derived from powder or grain, produced from carbon reduction of silica. It is produced as either fine powder or a large bonded mass, which is then crushed. To purify (remove silica) it is washed with hydrofluoric acid. There are three main ways to fabrie the commercial product.

Silicon Carbide Powder - online alogue source

Silicon Carbide was first prepared in the early 1800''s. It was in commercial production by 1892, as a powder for grinding and cutting, having a Mohs hardness of 9-10 (almost as hard as Diamond). Nicalon continuous multi-filament tow consists of fine filaments of ultra-fine ß-SiC crystals, giving strong particle bonding.

Panadyne Inc.: Silicon Carbide

Silicon Carbide also has the resistivity necessary to perform as a semiconductor material. Because of these properties, Silicon Carbide is used in a wide range of appliions and industries. Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace.
