What is the approximate price of monocrystalline silicon?
According to the latest data of June 5438+1October 65438+1October 0 1 in 2020, the price of monocrystalline silicon is about several hundred yuan per unit, ranging from cheap one or two hundred yuan to expensive several thousand yuan. Monocrystalline silicon has different functions and uses, and its price is also different.

Monocrystalline silicon has a rhombic lattice, which is hard and brittle, metallic and conductive, but its conductivity is not as good as that of metal, and it increases with the increase of temperature, so it has semiconductor properties.

Monocrystalline silicon can be used for the production and deep processing of diode-level, rectifier-level, circuit-level and solar cell-level single crystal products, and its subsequent products, integrated circuits and semiconductor separation devices, have been widely used in various fields, and also occupy an important position in military electronic equipment.

Main uses of monocrystalline silicon

Monocrystalline silicon is the raw material for manufacturing semiconductor silicon devices, which is used to manufacture high-power rectifiers, high-power transistors, diodes, switching devices and so on. When molten elemental silicon solidifies, silicon atoms are arranged into many crystal nuclei in the diamond lattice. If these crystal nuclei grow into grains with the same crystal plane orientation, these grains combine in parallel and crystallize into monocrystalline silicon.

The preparation method of monocrystalline silicon is usually to prepare polycrystalline silicon or amorphous silicon first, and then grow rod-shaped monocrystalline silicon from the melt by Czochralski method or suspension zone melting method.

Monocrystalline silicon rods are raw materials for producing monocrystalline silicon wafers. With the rapid increase in the demand for monocrystalline silicon wafers at home and abroad, the market demand for monocrystalline silicon rods is also growing rapidly.
