Silicon metal is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, which is an essential basic raw material in hi-tech industry. The classification of silicon metal is usually classified according to the content of iron, aluminum and calcium contained in the silicon metal components. According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into 553 441 411 421 3303 3305 2202 2502 1501 1101 and other different brands.

In industry, silicon metal is usually made by carbon reduction of silicon dioxide in the electric furnace chemical reaction equation: SiO2 + 2C Si + 2CO so that the purity of silicon metal is 97~98%, called silicon metal and then melt it after recrystallization, with acid to remove impurities, the purity of silicon metal is 99.7~99.8%.

The main component of metallic silicon is silicon, so it has similar properties to silicon. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties.

The classification of metallic silicon is usually based on the content of the three main impurities of iron, aluminum, and calcium contained in the metallic silicon component. According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.

 

 

Industrial metal silicon powder is often used in the metallurgical casting industry as a non-ferrous alloy additive and silicon steel alloy agent to increase the hardenability of steel. Industrial silicon metal powder can also be used as a reducing agent for certain metals, such as new ceramic alloys.

In the refractory and powder metallurgy industries, metallic silicon is often used in steelmaking furnaces, kilns and kiln furniture to improve the high temperature resistance, wear resistance and oxidation resistance of the products.

Monocrystalline silicon produced through industrial silicon purification can be used in high-tech production fields such as integrated circuits and electronic components.

High-purity metallic silicon is used in many industrial areas. It is used in the production of silicon compounds, photovoltaic solar cells and electronic semiconductor silicon wafers.

High-quality silicon metal can also be used to improve the properties of existing aluminum. These properties include castability, hardness and strength. Adding metallic silicon to aluminum alloys can make them strong and lightweight.

Silicon metal is increasingly used in the automotive industry. For example, as a replacement for heavier cast iron components to reduce body weight. Among them, automobile engine blocks, tires, and wheel hubs are common parts made of cast aluminum and silicon materials.
