497-19-8 | Sodium Carbonate (Na₂CO₃)

Chemical type

• Alkali metal carbonate

^[1]

• Inorganic Alkali Salt
• Fluxing Agent

^[2]

Key properties

• Source of CO₃²⁻ ions
• Drives metathesis reaction with SrSO₄

^[1]

• High-efficiency flux
• Decomposes to provide sodium ions (Na⁺)
• Forms low-melting-point eutectic compounds (e.g., with aluminosilicates)
• Reduces the melting point of gangue minerals
• Significantly reduces the Gibbs free energy (ΔG) of reduction reactions

^[2]

• Conversion of SrSO₄ to SrCO₃ via double ion replacement

^[1]

• Synergistic reduction roasting additive for red mud
• Facilitates melt-phase reconstruction to enhance porosity
• Catalyzes the conversion of refractory iron minerals (like Fe₃SiO₄ and FeAl₂O₄) to metallic iron
• Promotes the formation of sodium aluminosilicate phases (e.g., NaAlSiO₄), inhibiting the formation of olivine and spinel phases that hinder iron recovery

^[2]

Classification by use

• Precipitation and conversion reagents

^[1]

• Chemicals used in metallurgical processing
