CaSi2 Calcium Disilicide Powder CAS 12013-56-8

Calcium Disilicide (CaSi₂) is a high-reactivity intermetallic compound valued for its unique combination of metallurgical and chemical properties. This gray crystalline material serves as a powerful deoxidizer in steelmaking, a hydrogen-generation agent, and a precursor for advanced silicon-based materials. Its hygroscopic nature and controlled reactivity make it indispensable in industrial and energy applications.

High Reactivity: Rapid deoxidation and desulfurization in molten metal processing.
Hydrogen Yield: Produces 1.5 m³ H₂ per kg CaSi₂ in controlled hydrolysis.
Thermal Stability: Withstands temperatures up to 800°C in inert atmospheres.
Cost-Effective: Lower cost compared to rare-earth deoxidizers.
