Silicon Metal is also called industrial silicon or crystalline silicon.It is silver gray
with metallic luster, when be processed into powder the coloure si dark grey. It has high
melting point, good heat resistance and high resistivity.It is usually used in electro,
metallurgy and chemical industry. It is the indispensable essential raw material in the hi-
tech industry.

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 highttech field as an 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.
