Product Name:High quality metallic silicon 97

Product Introduction：

97 metal silicon refers to industrial silicon (Si), as the name suggests, which is about 97%, rather than high-purity products with a purity of over 99.9%. Its main impurities are iron (Fe), aluminum (Al), calcium (Ca), etc.

Silicon chemical reaction:

The mainstream method for obtaining elemental silicon in industrial production is high-temperature carbon reduction, with the core reaction being SiO ₂+2C - (high temperature>1900 ° C) → Si+2CO ↑. This process usually uses carbonaceous materials such as coal and sawdust as reducing agents to "take away" oxygen from quartz sand (mainly composed of SiO ₂), reacting to produce carbon monoxide gas and silver gray metallurgical grade silicon, with a silicon purity of about 97% -99%.

Product silicon content ratio:
Silicon (Si) content ≥ 97%, iron (Fe) content ≤ 1.2%-1.8%, aluminum (Al) content not directly constraining, calcium (Ca) content ≤ 0.3%-1%.(The smaller the other numbers, the fewer impurities, the higher the purity, and correspondingly higher the value).

Main purpose:
Metallic silicon is a key basic raw material for modern industry, mainly used in several fields. In the fields of semiconductors and photovoltaics, high-purity metallic silicon is used to manufacture chips and solar cells; In the field of organic silicon chemical industry, it has derived products such as silicone rubber and silicone oil. In metallurgy, it is an important additive for aluminum alloys and steel, which can improve the strength, wear resistance, and casting performance of materials. In addition, metallic silicon is also used to manufacture high-performance refractory materials. Its application runs through all aspects of daily life and work.

The role of silicon production process in smelting and casting:
The core applications of the high purity Silicon are concentrated in the fields of metallurgy and casting. As an additive in aluminum alloy production, it can improve the fluidity, strength, and corrosion resistance of the alloy. It is an important raw material for aluminum alloys and is widely used in the automotive, aviation, and construction industries. In steel smelting, 97 silicon is used as a deoxidizer to improve the density and cleanliness of steel, and is also used in the production of silicon steel. In addition, it can also be used as a reducing agent for the preparation of various alloys such as ferrosilicon and silicon manganese.
