Silicon Metal4407 processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemicalindustry. It is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance,highresistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.
Silicon Metal 4407 grade |
Silicon metal also called crystalline silicon or industrial silicon is mainly used as an additive for non-ferrous alloys. Metallic silicon has a high melting point, good heat resistance, high electrical resistivity, and ultra-high oxidation resistance. Si metal is a product smelted from quartz and coke in an electric furnace. The main component is Silicon, other impurities are iron, aluminum, calcium, etc. According to the content of Fe, Al and Ca in silicon metal be divided into many different grades, like 553、441、421、3303、2202、2502, etc.
It is also known as non silicon alloy for industrial use. According to the content of Fe, Al and Ca in metal silicon, the metal silicon can be divided into 553、441、421、3303、2202、2502, etc. Metal silicon additional products include silicon powder, metal silicon slag, etc. Among them, silica fume is also called silica fume, micro silica fume, or silica fume, which is widely used in refractory and concrete industries.
Silicon is widely used in smelting ferrosilicon alloy as alloy element in iron and steel industry and reducing agent in smelting many kinds of metals. Silicon is also a good component in aluminum alloy, and most casting aluminum alloys contain silicon.
Silicon is the raw material of ultra pure silicon in electronic industry. The electronic devices made of ultra pure semiconductor single crystal silicon have the advantages of small volume, light weight, good reliability and long service life.

Application |
1) Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
2) In the chemical line of organic silicon, industrial silicon powder is basic raw material that high polymer of organic silicon formatting.
3) Industrial silicon powder is sublimated into monocrystalline silicon, which is widely used in highttech field as an essential raw material for integrated circuit and electronic element.
4) 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 hardenability.
5) These are used in high-temperature material production in order to manufacture enamels and pottery. These also cater the demands of semiconductor industry by producing ultra-pure silicon wafers.
