Specification
Silicon Metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. It is a
product made by smelting quartz and coke in an electric furnace. The main element silicon content is about 98%, and the remaining
impurities are iron and aluminum, Calcium, etc.
our silicon metal is used by the chemical industry in the production of silicon compounds and by semiconductors. Aluminum
manufactures to improve the useful properties of aluminum, as well as in the manufacture of silicon wafers used in photovoltaic
solar cells and electronic.

1. industrial silicon powder is widely used in refractory materials and powder metallurgy industry to improve the high temperature
resistance,wear resistance and antioxidant properties of the products.Its products are widely used in steelmaking furnace,kiln and
kiln furnture.
2. Sillcon wafers processed by silicon wafers are widely used in high technilogy field.They are indispensable raw materials for
integrated circuits and clcetronic components.
3. In metallutgical industry,industrial silicon powder is used as a non iron base alloy additive and silicon steel alloy,so as to inprove
the hardernbllity of steel,Industrial silicon powder can also be used as a reductant for some metal,and it is used for new ceramic alloys
