Is metallic silicon the same as industrial silicon
Silicon metal with silica by reducing production is also called industrial silicon, silicon metal for nearly half a century to new products mainly export to Japan, the United States, Europe, Australia, India, South Korea, Malaysia, Hong Kong, Taiwan, Canada, Mexico, Argentina and other countries and regions due to high smelting metal silicon power consumption so silicon metal market price of the corresponding high silicon metal main impurities of iron, aluminum, calcium should be strictly control the iron, aluminum, mainly adopt two control before feeding test of silica, charcoal content of iron, aluminum, high silica can use charcoal to be selected using silica, charcoal before feeding (multi plant for water flushing) calcium control mainly adopts chlorine gas Access oxygen or oxygen out to eliminate iron and aluminum also has a role to the electronic, chemical industry, silicon metal of chromium, bismuth, lead, manganese, titanium, phosphorus, copper, carbon have silicon is in the nature of semiconductor crystal shape silicon with metallic luster appearance is light gray room temperature stability only very lively fluorine can directly with combined into four fluoride silicon generated under high temperature silicon also directly combined with too much carbon into sic smelting aluminum alloy when adding a small amount of purity 98% silicon metal greatly improves performance of the aluminum alloy 98 ~ 99% silicon metal to produce chemical hydrogen purity silicon products configuration hundreds of silicone lubricant between classes and waterproofing compound silicon metal and electronic industrial ultrapure silicon raw materials To produce monocrystalline silicon and polycrystalline silicon large-scale integrated circuit basic materials also used to produce optical fiber as a quality semiconductor material high purity monocrystalline silicon to manufacture efficient solar cells.
