硅金属

Silicon metal is used in manufacture of special steels and cast iron, aluminum alloys, glass and refractory materials, ceramics, abrasives, water filtration, component of hydraulic cements, filler in cosmetics, pharmaceuticals, paper, insecticides, rubber reinforcing agent - especially for high adhesion to textiles, anti-caking agent in foods, flatting agent in paints, thermal insulator. Fused silica is used as an ablative material in rocket engines, spacecraft, silica fibers used in reinforced plastics.Silicon metal is important to the electronic industry, as it is the base material used in the manufacture of high purity polycrystalline silicon. These products are used in the manufacture of semiconductors, microchips for computers and solar cells used to capture electrical energy from the sun.Silicon metalPlateChemical composition(%) Si(≥)Fe(≤)Al(≤)Ca(≤)Silicon metal 1101990.10.10.01Silicon metal 2202990.20.20.02Silicon metal 2502990.250.20.05Silicon metal 3303990.30.30.03Silicon metal 331990.30.30.1Silicon metal 441990.40.40.1Silicon metal 55398.50.50.50.3
