Quality Control

Our Hafnium Hydride is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase identification and inert gas fusion for hydrogen content analysis. A Certificate of Analysis (COA) detailing purity, particle size distribution (where applicable), and metallic impurities is provided with each shipment to meet the stringent requirements of our industrial partners.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 15-25°C. The container must be kept sealed to prevent exposure to air and moisture.
