Quality Control

Our Hafniumchloride is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through advanced analytical techniques including Inductively Coupled Plasma (ICP) and X-ray Diffraction (XRD). A comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and physical characteristics is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, containers must be kept sealed under an inert atmosphere (argon or nitrogen) to prevent moisture absorption and degradation. Keep away from incompatible materials.
