[Carborundum] Originally a registered trademark that is now used for several artificial abrasives made from Silicon carbide, fused Alumina, and other materials. Edward Atcheson accidentally made Carborundum in 1884 when he was attempting to synthesize diamonds from Clay and Coke. He patented the material in 1893 and trademarked it under the name Carborundum, a variant of Corundum, because he incorrectly believed his compound contained Carbon and Aluminum oxide. His product was, however, was composed of silicon carbide which has a Mohs' hardness scale of 9.17. Now many varieties of Carborundum are available with varying hardness and grit. Carborundum abrasives are used for cutting, grinding and polishing all kinds of metal and glass.
