Quality Control

Our Phosphoric Acid, Zirconium Salt is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications, including assessment of zirconium content, phosphate content, particle size distribution, and impurity levels. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and quality assurance for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture. Separate from strong acids, strong bases, and fluorides.
