Chemical applications include:
Silicon metal is used to produce silicones, synthetic silica and silanes. Silicone products such as surfactants, lubricant, sealants and adhesives are used in various sectors including construction (e.g., in insulating rubbers), industrial processes (e.g. as an antifoam agent in the oil and gas industry), and in personal care (e.g. cosmetics) and transport (CES, 2016). Silanes are used in the glass, ceramic, foundry and painting industries (European Commission, 2014; Euroalliages, 2016).
Technical applications include:
Aluminium alloys. Silicon is dissolved in molten aluminium to improve the viscosity of the liquid aluminium and to improve the mechanical properties of aluminium alloys.
Solar cells. Ultrahigh-purity grade silicon is used for the production of solar panels. Silicon solar cells are the most common cells used in commercially available solar panels.
Electronics. Ultra-high purity grade silicon is used extensively in electronic devices such as silicon semiconductors, transistors, printed circuit boards and integrated circuits. Semiconductor-grade silicon metal used in making computer chips is crucial to modern technology.
Other applications of silicon metal include explosives, refractories and ceramics.
Production Process of Si Metal
The majority of silicon refined each year - about 80 percent - is produced as ferrosilicon for use in iron and steelmaking. Ferrosilicon can contain anywhere between 15 and 90 percent silicon depending on the requirements of the smelter.
The alloy of iron and silicon is produced using a submerged electric arc furnace via reduction smelting. Silica-rich ore and a carbon source such as coking coal (metallurgical coal) are crushed and loaded into the furnace along with scrap iron.
At temperatures over 1900°C (3450°F), carbon reacts with the oxygen present in the ore, forming carbon monoxide gas. The remaining iron and silicon, meanwhile, then combine to make molten ferrosilicon, which can be collected by tapping the base of the furnace. Once cooled and hardened, the ferrosilicon can then be shipped and used directly in iron and steel manufacturing.
The same method, without the inclusion of iron, is used to produce metallurgical grade silicon that is greater than 99 percent pure. Metallurgical silicon is also used in steel smelting, as well as the manufacture of aluminum cast alloys and silane chemicals.
Metallurgical silicon is classified by the impurity levels of iron, aluminum, and calcium present in the alloy. For example, 553 silicon metal contains less than 0.5 percent of each iron and aluminum, and less than 0.3 percent calcium.
