All silicon metal shares a common origin: Quartz (SiO2). Quartz is reduced to silicon (Si) in a high temperature melting process using carbon and quartz in an electric arc furnace.The main component of silicon is about 98% (in recent years, the purity can reach above 99.99%), other impurities are:Ferrum,Aluminum, Calcium.According to the content of these impurities,we categorize metal silicon into different grades: 1101, 1501, 2202, 2502, 3303, 411, 421, 441, 553
