    How to make better use of silicon carbide? | .

    American inventor Edward C. Acheson first discovered silicon carbide in 1891 in order to get rich by making synthetic diamonds. Unable to make diamonds by heating carbon too much, he used the heat of a powerful power plant to inject carbon into clay to produce lustrous hexagonal crystals that were strong enough to scratch glass, which he called emery.

    History | ESD-SIC bv

    Silicon carbide (SiC) was discovered by chance in 1891 by the American Acheson in his attempts to make artificial diamond. Unlike many alchemists who preceded him, his efforts were not entirely without result. During his experiments, dark, irregular crystals were formed with a hardness only matched by diamond and boron carbide.

    The Acheson process is a process to synthesize graphite and silicon carbide, named after its inventor Edward Goodrich Acheson.. The process consists of heating a mixture of silica or quartz sand and powdered coke (carbon) in an iron bowl. Acheson, in 1890, originally attempted to synthesize artificial diamond, but ended up creating blue crystals of silicon carbide, which he called carborundum.
