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

Silicon Metal 411 Application
1.Most metallurgical silicon metal is used as an alloying agent in the aluminium industry due to its ability to increase the strength of aluminium alloys as well as to reduce its weight;
2.Metal Silicon is the raw material of ultra pure silicon in electronic industrial,playing an important role in making electronic devices and solar cells;
3. Used in organic chemicals:Silicon metal is used in manufacturing a number of sorts of silicones, resins, and lubricants, silicone rubber,thereby enhancing the heat resistance, electrical insulation, corrosion resistance, water tightness and other characteristics.
4. Solar industry and electronics industry
Silicon metal can also be used as essential material in the solar and electronics industries. For examples, it can be used in the manufacture of solar panels, semi-conductors and silicon chips.
