Silicon carbide: Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found appliion
Although metallic boron has very few uses, the element is highly valued in a nuer of metallurgical appliions. By removing carbon and other impurities as it bonds to iron, a tiny amount of boron—only a few parts per million—added to steel can make it four times stronger than the average high-strength steel.
