Silicon carbide was discovered in 1891 by the American inventor Edward G. Acheson while he was attempting to create artificial diamonds. By heating a mixture of clay and powdered coke in an iron bowl using a carbon arc-light, he produced bright green, hexagonal crystals.12

Acheson initially believed these crystals were a new compound of carbon and alumina derived from the clay. Because the natural mineral form of alumina is known as corundum, he coined the trademark name Carborundum for his discovery. Although he later realized the compound was actually silicon carbide, the name persisted as a trademark for the material, which became widely used as an industrial abrasive due to its extreme hardness.123
