Details information
Silicon is a metalloid and carries the typical properties of both metals and nonmetals. It is extremely inert and insoluble in water and acids. However, it can be dissolved into silicates by hot alkaline lyes. Pure silicon forms dark gray, metallic, shiny crystals. Silicon also has excellent thermal conductivity, which – in pure silicon – is accompanied by extremely low electrical conductivity. When alloyed with aluminium, it enhances strength and reduces weight
Silicon metal has high melting point, good heat resistance, high resistivity and high oxidation resistance
Industrial silicon (also named silicon metal), is silver gray or dark gray with metallic luster.Featured by high fusing point, good heat-resistance, high resistivity and high antioxidation, it is well known as “industrial monosodium glutamate” and an indispensable raw material in hi-tech industry.
Applications:
* Silicon Metal powder is regarded as alloy additive, improve the steel hardenability
in metallurgy and foundry industry.
* 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.
* 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.
* Silicon Metal is widely used in smelting alloy elements,as a reducing agent in many kinds of
metal smelting.
* Silicon metal is widely applied to refractory material and power metallurgy industry to
improve the heat resistance, wear resistance and oxidation resistance.
