Quality Control

Our Rare Earth Fluoride is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and high performance. Each lot is analyzed for critical parameters including purity, metallic impurities, and particle size distribution where applicable. A comprehensive Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and bases. Due to its fluoride/strong alkali nature, ensure storage containers are compatible and segregated from reactive substances. Recommended storage temperature is 15-25°C.
