What is metal silicon?
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 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.
Silicon metal manufacturing process
1.In China, Silicon metal lump is widely used in smelting alloy elements,as a reducing agent in many kinds of metal smelting.
2.Silicon metal lump widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
3. Silicon powder is regarded as alloy additive, improve the steel hardenability in metallurgy and foundry industry.
4.It is mainly used in production of alloys,polycrystalline silicon,organic silicon materials and high-grade refractor .

Silicon metal uses
Mainly used in the steel industry and foundry industry.
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 lump is used in manufacturing a number of sorts of silicones, resins, and lubricants.
3. Used in electronic parts: Silicon metal lump is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
