Quality Control

Our Tungsten Nitride is manufactured under controlled conditions to ensure batch-to-batch consistency and high performance. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase purity, elemental analysis for stoichiometry, and particle size analysis. A Certificate of Analysis (COA) detailing specific lot results is provided with each shipment.

Storage

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