Description

Ferrous Hexafluorosilicate is an inorganic salt of iron and hexafluorosilicic acid, identified by CAS No. 12062-25-8. This compound serves as a critical source of bioavailable iron and soluble fluoride ions for specialized industrial and chemical synthesis processes. It is primarily utilized by manufacturers in the water treatment, ceramics, and metallurgical industries seeking controlled fluoridation and iron supplementation.

Application

• Water Fluoridation and Treatment: Used as a source of fluoride ions for municipal water treatment and as a flocculant aid.
• Ceramics and Enamel Production: Acts as a fluxing agent and opacifier in the manufacture of ceramics, porcelain, and vitreous enamels.
• Metal Surface Treatment: Employed in metal finishing and surface conversion coatings, particularly for steel, to enhance corrosion resistance and paint adhesion.
• Chemical Synthesis: Serves as a precursor or catalyst in the synthesis of other fluorosilicate compounds and specialty chemicals.
• Wood Preservation: Used in formulations for timber treatment due to its fungicidal and insecticidal properties.
• Agriculture (Specialized): Applied in specific micronutrient formulations where both soluble iron and fluoride are required, subject to strict regulatory approval.
