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.
Function
1.Silicon Metal is often used as deoxidizer in steel making.
2.Silicon Metal can be used as used as diodes, transistors, thyristors and various integrated circuit materials.
3.Silicon Metal can make solar cells.

Applications
1. Silicon Metal is used in large quantities to smelt ferrosilicon alloy as an alloying element in the steel industry and as a reducing agent in the smelting of many metals.
2. In organic silicon chemical operations, granular & powder silicon metal is a base material used in the synthesis of organic silicon products. It is often used to manufacture silicon monomers, silicone oils, and silicone rubber preservatives. As an additive, this product provides a significant increase in temperature resistance, electrical insulation, corrosion resistance, waterproofness, and many more highly valuable properties.
3. Some of the more valuable applications of silicone metal involve using silicon wafers to produce integrated circuits and other electronics components. The granule & powder undergoes a drawing process, turning it into monocrystalline silicon wafers. High-tech industries are essentially driven by silicon.
