A wide range of uses of metallic silicon
Silicon (Si) is an extremely common element, accounting for 26.4% of the Earth's crust, second only to oxygen 49.4%. However, silicon rarely appears in the form of a single substance in nature, but in the form of complex silicates or silica, which is widely present in rocks, gravel, and dust. Elemental silicon is made of quartz and coke smelted in an electric furnace, called metallic silicon, also known as crystalline silicon or industrial silicon, the content of the main component silicon element is about 98%, and the remaining impurities are iron, aluminum, calcium and so on.
Mainly used as an additive for non-ferrous alloys. Silicon metal is widely used, mainly for metallurgical deoxidation, aluminum alloy, and the production of polysilicon, monocrystalline silicon. It is also used to make high-purity semiconductors, high temperature resistant materials, optical fiber communication materials, silicone compounds, which are widely used in aerospace, electronic appliances, construction, transportation, energy, chemical, textile, food, light industry, medical, agricultural industries and so on
