Quality Control

Our Zirconium Silicate is produced under a rigorous quality management system to ensure batch-to-batch consistency and performance. Quality parameters including chemical purity, particle size distribution, and specific gravity are strictly monitored. Certificates of Analysis (COA) documenting these specifications are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong acids and strong oxidizing agents. The product is not hygroscopic under normal conditions but should be protected from prolonged exposure to moisture to prevent caking.
