Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth's crust (behind only oxygen) and the eighth-most common element in the universe.
Silicon metal is also called crystalline silicon or industrial silicon. The deoxidation efficiency of silicon metal is very high, and it is often used as the raw material of ferrosilicon alloy.
Silicon metal acts as a reducing agent in many metal smelting processes. In steelmaking production, pure silicon metal can increase furnace temperature, increase molten iron fluidity, and improve the toughness and cutting ability of castings.
Silicon metal, also known as industrial silicon, is mainly used as an additive for non-ferrous alloys. It is a product smelted from quartz and coke in an electric furnace, with the main component of silicon about 98% or 99.99%, and the remaining impurities of iron, aluminum, calcium, etc.
Silicon metal is usually classified according to the content of three main impurities of iron, aluminum and calcium into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and so on.
Silicon metal is usually classified according to the content of Si, Fe, Al, Ca. Main types of silicon metal are Si 553, Si 441, Si 411, Si 421, Si 3303, Si 3305, Si 2202, Si 2502, Si 1501, Si 1101 etc.
Silicon Metal is processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical industry. It is silver gray or dark gray with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance. Metal Silicon is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. It's known as the "salt" of modern industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products. The main ingredient of silicon content is about 98%. The rest of impurities is iron, aluminum and calcium etc.
Silicon Metal is Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
In the chemical line of organic silicon, industrial silicon powder is basic raw material that high polymer of organic silicon formatting.
Industrial silicon powder is sublimated into mono crystalline silicon, which is widely used in highttech field as an essential raw material for integrated circuit and electronic element.
In metallurgy and foundry line, industrial silicon powder is regarded as to be iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel harden ability.
Silicon metal is used in the production of high-temperature materials.
