Strong Oxidation Resistance Ferro Silicon
Ferrosilicon is an alloy material, mainly composed of silicon and iron, its chemical formula is FeSi. It is a very important industrial raw material, widely used in steel, alloy, electronics, chemical and other fields. Ferrosilicon not only has good mechanical properties and conductive properties, but also has the characteristics of not easy to be oxidized, corrosion and wear, can maintain long-term stable performance.
Description
Description
The physical properties of ferrosilicon are mainly related to its crystal structure. Ferrosilicon crystal structure is face-centered cubic crystal, silicon and iron atoms occupy different lattice points respectively.
The crystal structure of ferrosilicon is compact and orderly, and the distance between atoms is small, so its density is larger, hardness is higher, and it is not easy to be oxidized and corroded. In addition, ferrosilicon also has good conductivity, is an excellent electromagnetic material.
The chemical properties of ferrosilicon are mainly related to the properties of its constituent elements. Both silicon and iron are chemically inert and do not react easily with other elements.
Therefore, ferrosilicon is not easy to be oxidized and corroded at room temperature. When ferrosilicon is exposed to air, a dense oxide film will be formed on its surface, which can effectively prevent the oxidation reaction, so as to protect the performance of ferrosilicon.

The mechanical properties of ferrosilicon are mainly related to its crystal structure and constituent elements. Ferrosilicon crystal structure is tight and orderly, the distance between atoms is small, so the hardness is higher, not easy to be worn. In addition, the composition of ferrosilicon iron has good plasticity, can make ferrosilicon has a certain plasticity and toughness.
Take automobile manufacturing as an example, many parts in modern automobile are made of silicon iron, such as engine cylinder block, crankcase, connecting rod and so on. This is because ferrosilicon is not easy to deformation, not easy to wear, corrosion resistance, high temperature resistance and other excellent mechanical properties, can ensure the long-term stable operation of the car.
In addition, ferrosilicon also has good thermal conductivity, can make the automobile engine fast heat dissipation, reduce the engine temperature, protect the performance of the engine. Therefore, ferrosilicon has important application value in automobile manufacturing.
