The application of silicon
The atomic structure of silicon determines that silicon atoms have certain electrical conductivity. However, because there is no obvious free electron in silicon crystals, the electrical conductivity is lower than that of metals, and it increases with the increase of temperature, so silicon atoms have semiconductor properties. The commercial silicon is usually divided into metal silicon and semiconductor silicon in the world. The metal silicon is mainly used to make polycrystalline silicon, monocrystalline silicon, silicon aluminum alloy and silicon steel alloy compounds. Semiconductor silicon is used to make semiconductor devices. Generally speaking, silicon is mainly used to make high-purity semiconductors, high-temperature resistant materials, optical fiber communication materials, organosilicate compounds, alloys, etc. It is widely used in aerospace, electronics and electricity, construction, transportation, energy, chemical industry, textile, food, light industry, medical treatment, agriculture and other industries.
