How is silicon metal made
Websilica, also called silicon dioxide, compound of the two most abundant elements in Earth ’s crust, silicon and oxygen, SiO 2. The mass of Earth’s crust is 59 percent silica, the main constituent of more than 95 percent of the known rocks. Silica has three main crystalline varieties: quartz (by far the most abundant), tridymite, and cristobalite. WebCarbon electrodes are most largely used for the production of silicon metal. The process consists in the continuous reduction of quartz (SiO2) into silicon by a reducing mixture according to the simplified relation SiO2, + 2C -> Si + 2CO.
