Silicon Application Profile
The atomic structure of silicon determines that silicon atoms have a certain degree of electrical conductivity, but because there are no obvious free electrons in silicon crystals, the electrical conductivity is not as high as that of metals and increases with temperature, hence its semiconductor nature. Internationally, commercial silicon is usually divided into silicon metal and silicon semiconductor. Silicon metal is mainly used to make polycrystalline silicon, single crystal silicon, silicon aluminum alloy and silicon steel alloy compounds. Semiconductor silicon is used to make semiconductor devices. Overall, silicon is mainly used to make high-purity semiconductors, high-temperature resistant materials, optical fiber communication materials, silicone compounds, alloys, etc. It is widely used in aerospace, electrical and electronic, construction, transportation, energy, chemical, textile, food, light industry, medical, agricultural and other industries.
