What is Potassium fluorozirconate?
Potassium fluorozirconate (CAS 16923-95-8), also known as potassium hexafluorozirconate or zirconium potassium fluoride, is an inorganic zirconium salt used in metal treatment and surface finishing.
Where is Potassium fluorozirconate used?
- Industrial process formulations and specialty chemical manufacturing: corrosion inhibitor and biocide
- Metal surface treatment: flux and grain refiner in aluminum processing
- Magnesium alloy processing: improves adhesion for downstream coating and anodizing
- Mining and metals: zirconium refining and fluoride source in electrolytic processes
- Textile and leather treatment baths: controlled fluoride release supports fiber fixation and preservation against microbial degradation
- Personal care manufacturing: zirconium-based antiperspirant or preservation activity
- It is a white crystalline powder for handling in industrial settings.
Commercial specifications
- Technical grade, purity typically 98% to 99%+
- Bulk packaging for industrial procurement and large-scale chemical distribution
- Documentation commonly provided for import and quality assurance requirements
