Steelmaking Silicon Metal 421/553/97 Lump / Granule / Powder
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.
Metallurgical silicon typically contains impurities such as iron, aluminum, calcium, and carbon, which are introduced during the production process. These impurities are present in relatively higher concentrations compared to other forms of silicon, such as semiconductor-grade silicon used in electronics.
Product Details
Silicon Metal processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical industry. It 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, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.

Applications
Alloying Agent: Metallic silicon is primarily used as an alloying agent in the production of aluminum alloys. It is added to molten aluminum to improve its strength, hardness, and casting properties. Silicon helps control grain size and improves the fluidity of the molten metal, making it easier to cast into various shapes.
Silicone Production: Metallic silicon is a key raw material in the production of silicones, which are versatile polymers used in a wide range of applications. Silicones have properties such as heat resistance, water repellency, and flexibility. They are used in sealants, adhesives, lubricants, electrical insulation, medical devices, cooking utensils, and various other products.
