Description
Crystalline silicon is grey-black, metallic luster, hard and brittle solid, electrical conductivity between the conductor and insulator, is a good semiconductor material, density 2.32-2.34g/cm3, melting point 1410 ℃, boiling point 2355 ℃
The atomic structure of silicon determines that silicon atoms have a certain degree of electrical conductivity, but due to the absence of obvious free electrons in silicon crystals, the electrical conductivity is less than that of metals and increases with temperature, thus having semiconductor properties. Internationally, commercial silicon is usually divided into silicon metal and semiconductor silicon, silicon metal is mainly used to make polycrystalline silicon, monocrystalline silicon, silicon-aluminium alloys 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 fibre communication materials, silicone compounds, alloys, etc., and is widely used in the aerospace, electrical and electronic, construction, transportation, energy, chemical, textile, food, light industry, medical, agricultural and other industries.
