Product Description

Barium-silicon alloy is an inorganic compound, usually with the chemical formula BaSi₂. Composed of barium (Ba) and silicon (Si), it belongs to the metal silicide family and usually contains a certain amount of iron and other impurities.

• Physical Properties: Generally, it is a bulk metallurgical material, presenting as a gray-black crystalline solid. Its density is approximately 4.3 g/cm³, and its melting point is around 1200°C.
• Chemical Properties: It has strong deoxidation and desulfurization capabilities. During the steelmaking process, it can react with oxygen and sulfur in the molten steel. When reacting with water and acids, it produces silane (SiH₄) and barium compounds.
• Metallurgical Properties: Barium in the barium-silicon alloy can improve the deoxidation efficiency of silicon, reduce the oxygen content in the molten steel, prevent the formation of harmful nodules, promote the formation of spherical inclusions, and improve the fluidity and quality of the steel.

Applications

• Steelmaking Field: Used as a deoxidizer to remove oxygen from the molten steel, thereby improving the strength and durability of the steel. It also serves as a desulfurizer to reduce the sulfur content in the steel, preventing brittleness and crack formation of the steel. Additionally, it can be used for inclusion modification to enhance the toughness and workability of the steel.
• Foundry Industry: Applied in the production of cast iron, it can improve the fluidity of the molten iron, reduce shrinkage, and enhance the mechanical properties of the castings.
• Special Steel Production: It is a crucial additive for manufacturing high-quality alloys used in industries such as automotive, aerospace, and construction.
