Product Description

Brief introduce of silicon metal:

• Silicon metal (symbol Si), in its pure form, is a grey metallically lustrous metalloid element. Metallurgical grade silicon is known as silicon metal because of its lustrous appearance.
   

• Silicon is used mainly in the manufacture of silanes and silicones, as a "hardener" or alloying element to produce aluminium alloys, and in the manufacture of micro-processors and solar cells.
   

• Silicon is also used as a secondary smelting additive in the manufacture of photonic devices and in the manufacture of industrial refractories.
   

• Silicon metal is commonly produced by smelting submerged electric arc furnaces, which is an energy-intensive process. Further processing of the material into different product grades makes it applicable in many industry processes.
   

• The industry is investing in R&D, a.o. for the development of high value silicon bound to the photovoltaic market, and in the battery applications.

Silicon Metal Lumps Application

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

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

5.Metalic silicon is 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
