Description

Sodium Fluorozirconate is an inorganic salt of zirconium and fluorine, widely recognized for its role as a key source of soluble zirconium and fluoride ions in industrial processes. Its primary value lies in its ability to impart hardness, corrosion resistance, and specific chemical functionalities to materials. This compound is essential for manufacturers in the metal finishing, ceramic, and glass industries seeking to enhance product performance and durability.

Application

• Metal Surface Treatment: A critical component in aluminum anodizing and conversion coating baths to improve corrosion resistance and paint adhesion.
• Abrasive & Grinding Wheel Manufacturing: Used as a bonding agent in vitrified grinding wheels and abrasive tools.
• Specialty Glass & Ceramics: Acts as a flux and opacifier in the production of heat-resistant, opaque glasses and ceramic glazes.
• Foundry & Casting: Employed in mold washes and refractory coatings to improve surface finish and metal penetration resistance.
• Welding Flux Formulations: Contributes to the stability and performance of fluxes used in submerged arc and other welding processes.
• Catalyst & Chemical Synthesis: Serves as a precursor or catalyst in specific organic fluorination and inorganic synthesis reactions.

Quality Control

Our Sodium Fluorozirconate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with agreed specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to prevent moisture absorption and caking. Recommended storage temperature is between 15°C and 25°C.
