I believe that most people, like Shengchi Ferroalloy, know the name of silicon metal, but don't know its essence. Silicon metal, commonly known as crystalline silicon or industrial silicon, is smelted from quartz and coke in an electric furnace. The main component of the product is about 98%, and the remaining impurities are iron, aluminum, calcium, etc.
Silicon metal is usually classified according to the content of iron, aluminum, and calcium contained in silicon metal. According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into silicon metal 553, silicon metal 441, and silicon metal. 411, silicon metal 421, silicon metal 3303, silicon metal 3305, silicon metal 2202, silicon metal 2502, silicon metal 1501, silicon metal 1101 and other different grades of silicon metal.
Speaking of the use of silicon metal, it is nothing more than steel smelting or refractory materials, and it is usually used as a reducing agent for many kinds of metal smelting. Silicon is the raw material of ultra-pure silicon in the electronics industry. Electronic devices made of ultra-pure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability and long life. High-power transistors, rectifiers and solar cells made of silicon single crystals doped with specific trace impurities are better than those made of germanium single crystals. Research on amorphous silicon solar cells is progressing rapidly, with a conversion rate of over 8%.
