CARBORUNDUM - Raven Crystals
ATTRIBUTES: Carborundum is a man made crystal also known as Silicon Carbide. In 1891, Edward Goodrich Acheson discovered Carborundum in an attempt to create diamond using electricity. Carborundum is composed of carbon and silicon atoms with strong bonds in a crystal lattice formation producing a very strong and hard material, insoluble in water or any solvent.
Silicon carbide — Wikipedia Republished // WIKI 2
Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).
