Quality Control

Our Niobium Nitride is manufactured under stringent quality management protocols. Each batch undergoes comprehensive analysis to verify critical parameters such as phase purity, particle size distribution, and metallic impurity content. We provide Certificates of Analysis (COA) with detailed specifications to ensure traceability and batch-to-batch consistency, meeting the rigorous demands of advanced material applications.

Storage

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