Silicon metal Description
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, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.
Silicon metal is important to the electronic industry, as it is the base material used in the manufacture of high purity polycrystalline silicon. These products are used in the manufacture of semiconductors, microchips for computers and solar cells used to capture electrical energy from the sun.Speciafication:ItemNoSi:%MINFe:%MAXAl:%MAXCa:%MAXP2202990.20.20.0240ppm2202990.20.20.02100ppm3303990.30.30.033305990.30.30.05441990.40.40.155398.50.50.50.3Size:10-100mm90%min
