Carborundum was first discovered by Edward Goodrich Acheson in 1891 when he was attempting to create artificial diamonds. Acheson's experiments led to the accidental synthesis of silicon carbide, which he named carborundum after the Latin word "carbo," meaning carbon, and the English word "corundum," a naturally occurring mineral.
