The composition content of Silicon Metal 3303 is usually silicon (Si) ≥ 99.37%, iron (Fe) ≤ 0.3%, aluminum (Al) ≤ 0.3%, and calcium (Ca) ≤ 0.03%. It usually exists in the form of irregular blocks of 10-100nm. This is also the standard particle size of the product Si-3303.

The technical parameters of metal silicon 3303 indicate that it has a high melting point, good heat resistance and resistivity, and a high degree of oxidation resistance. These properties make silicon 3303 widely used in industrial fields such as metallurgy, chemicals, petroleum, machinery manufacturing, silicate, and power.

It is widely used in industres, for instance in the manufacturing of silicon polished wafers, solar cells and high-purity silicon products. In addition, it is a basic raw material for the information industry and new energy industry. It is a raw material for the production of polysilicon and organic silicon.

In refractory materials, silicon metal can react with oxygen to form a new mineral phase to seal the pores, increase the density of the material, and prevent the penetration of slag iron. This characteristic of Si metal 3303 can improve the high temperature resistance, wear resistance and oxidation resistance of the product. Therefore, it is also a raw material for the production of high-grade refractory materials.

Silicon metal 3303 is also a good additive for non-iron-based alloys. In the aluminum alloy casting process, adding silicon can improve the high-temperature fluidity and wear resistance of the alloy, while reducing shrinkage and hot cracking tendencies.

Comparing to similar models like silicon 441 or silicon metal 553, the purity of Si content is higher in it. As a result, Silicon metal 3303 price is also higher than other regular models.
