Main application of industrial silicon:
The industrial silicon also called silicon metal, its main application is the additive agent of non-ferrous alloy. When putting the silicon into some nonferrous metal, it can improve the matrix metal's strength, solidity and abrasion performance and sometimes can improve the casting property and welding performance. Industrial silicon also can be used in silicon steel making which is required strict alloy agent, and used as deoxidizer for smelting special steel and nonferrous matrix alloy. After a series of processing treatment, the industrial silicon can be made to be monocrystalline silicon for electronic industry.
