Description

Products Description

Pure metal silicon smelting belongs to high silicon production has been a long time, with the tightening of the national energy policy and the development of energy conservation and emission reduction, as well as the promotion of new energy, metal silicon smelting has become a primary product and process, many domestic emerging energy enterprises have built a series of metal silicon, polysilicon, monocrystalline silicon, solar cells and other circular industrial chain. The next few years will inevitably affect the development of the entire energy field and the application of new energy in our country.

high purity silicon metal

Silicon is the chemical element that corresponds to the atomic number 14. This element is denoted by the symbol 'Si'.

It belongs to group 14 of the modern periodic table. It is a part of the carbon family.

Silicon is known to be a p-block element. Its electronic configuration is given by [Ne]3s²3p². Since the valence electrons of this element fall under the 3p subshell, this element can be classified as a p-block element.

Silicon has a total of four electrons in its outermost shell.

Under standard conditions for temperature and pressure, silicon is known to exist in the solid phase.

The melting point of silicon is approximately equal to 1687 Kelvin. Converting this Kelvin value into Celsius, the melting point of silicon can be expressed as 1414 degrees Celsius.

The boiling point of silicon is approximately equal to 3538 Kelvin. Converting this Kelvin value into Celsius, the boiling point of silicon can be expressed as 3265 degrees Celsius.

Under ambient conditions, the density of this element is roughly equal to 2.57 grams per cubic centimetre.

Silicon has an electronegativity of 1.9 on the Pauling scale.

Product parameters

Silicon is classified as a metalloid since some of its properties are similar to those of metals and some of its properties are similar to those of nonmetals. For example, silicon is known to have a bluish-grey metallic lustre but is not an amazing conductor of electricity. This element is classified as a semiconductor.
