Applications

Semiconductors: Silicon is a key part in semiconductors, which are used in a wide scope of electronic devices, for instance, computers, smartphones, televisions and so forth. Graphite electrodes are used when produce high-purity silicon in semiconductor manufacturing field.

Solar cells: Silicon is used while produce solar cells, too, and solar cells are used to produce renewable energy from the sun. Graphite electrodes are used when produce high-purity silicon for solar cell manufacturing.

Aluminum alloys: Silicon is used as an alloying element in the production of aluminum alloys, which are used in a variety of applications, such as aerospace, automotive, and construction. Graphite electrodes are used while manufacture silicon metal for aluminum alloy making.

Chemicals: Silicon is used when produce many kinds of chemicals, for example, silicones, silanes, and silicates. Graphite electrodes are used while produce high-purity silicon for chemical manufacturing.

Steel making: Silicon is used as a deoxidizing agent in steel making, where it helps to eliminate impurities from steel. They are used in when produce silicon metal for use in steel making.
