Silicon metal is a product of high quality silicon ore and coke smelted in an electric furnaces. Used in electro, metallurgy and chemical industry. It is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry. Product use 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.
1. Used in aluminum: an additive to aluminum alloys, silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly. 2. Used in organic chemicals: silicon metal is used in manufacturing a number of sorts of silicones, resins, and lubricants. 3. Used in electronic parts: silicon metal is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc. In plastic woven bags of about 10KG,250 KG and 1MT net each.
