What is Silicon Metal?
Metallic silicon, also known as metallurgical-grade silicon or simply metallurgical silicon, is a form of silicon that is primarily used in the production of aluminum alloys and silicones. It is produced through the reduction of silica (SiO2) with carbon in an electric arc furnace, resulting in a high-purity silicon product.
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.
Function
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 be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.

Applications
1. Used in aluminum: An additive to aluminum alloys, silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly.
2. Used in organic chemicals: Silicon metal is used in manufacturing a number of sorts of silicones, resins, and lubricants.
3. Used in electronic parts: Silicon metal is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
4.Metallic silicon is used as a raw material in the production of high-temperature-resistant ceramic materials, such as silicon carbide (SiC) and silicon nitride (Si3N4).
