Silicon metal, also known as industrial silicon, is silicon extracted from quartz (SiO₂) by electrothermal methods. Its main component is silicon (Si), and usually contains small amounts of impurities such as iron, aluminium and calcium. Silicon metal has a silvery grey appearance with a metallic luster and is brittle.
