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.
The main component silicon content is about 98%(in recent years, 99.99% of Si content is also included in metal silicon), and the remaining impurities are iron and aluminum., calcium, etc.
Function
Silicon Metal processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical 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. Additives for non-ferrous alloys, industrial silicon is also used as an alloying agent for siliconsteel with strict requirements, and as a deoxidizer for smelting special steels and non-ferrous alloys.
4.In the chemical industry, it is used to produce organosilicon products such as silicone rubber.silicone resin, and silicone oil. Silicone rubber has good elasticity and high-temperature resistance.making it suitable for manufacturing medical supplies, high-temperature gaskets, etc.
