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.
