Product Description
High Efficient Metallurgical Grade Silicon Metal 553/2202 Metal Silicon For Cast Iron
What is Silicon Metal?
Metallic silicon, also known as metallurgical-grade silicon or simply metallurgical silicon, is a form of silicon primarily used in aluminum alloy and silicone production. It's manufactured through silica (SiO₂) reduction with carbon in an electric arc furnace, resulting in high-purity silicon with a boiling point of approximately 2,800°C.
Key Characteristics
Silicon Metal appears as silver gray or dark gray powder with metallic luster, featuring:
- High melting point
- Excellent heat resistance
- High resistivity
- Superior oxidation resistance
Processed from premium industrial silicon, it's widely used in electro, metallurgy, and chemical industries.
