Description

Potassium fluorozirconate (CAS 16923-95-8 ), also known as potassium hexafluorozirconate or zirconium potassium fluoride, is an inorganic zirconium salt used across metal treatment and surface finishing. It functions primarily as a corrosion inhibitor and biocide in industrial process formulations and specialty chemical manufacturing. In metal surface treatment, it serves as a flux and grain refiner in aluminum processing. The compound improves adhesion for downstream coating and anodizing operations in magnesium alloy processing. The mining and metals sector uses it in zirconium refining and as a fluoride source in electrolytic processes. Textile and leather processors incorporate it into treatment baths where controlled fluoride release supports fiber fixation. This application also provides essential preservation against microbial degradation during the manufacturing cycle. In personal care manufacturing, it appears in formulations requiring zirconium-based antiperspirant or preservation activity. The material is supplied as a white crystalline powder for easy handling in industrial settings. Technical grade is the standard commercial form, with purity levels typically ranging from 98% to 99%+. Packaging is available in bulk quantities suited to industrial procurement and large-scale chemical distribution. Documentation is commonly provided to meet import and quality assurance requirements for global logistics. This ensures compliance with safety standards and technical specifications for diverse manufacturing applications. Contact us for supply of Potassium fluorozirconate Request Quote
