99.99% Si Granule Silicon Metal/ Si For Optical Coating

Product Overviews

Silicon Metal is also called industrial silicon or crystalline silicon,it is dark gray.Its characteristics are high melting point, good heat-resisting, high resistivity and excellent anti-oxidation.

1.Silicon metal is widely used in smelting alloy elements,as a reducing agent in many kinds of metal smelting.

2.Silicon metal is widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.

3.Silicon metal powder is regarded as alloy additive, improve the steel hardenability in metallurgy and foundry industry.

4.Industrial Silicon metal powder is sublimated into monocrystalline silicon, which is widely used in high tech field as essential  raw material for integrated circuit and electronic element.

5.Silicon metal 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.
