Quality Control

Our Holmium Hexaboride is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including X-ray diffraction (XRD) for phase purity and inductively coupled plasma (ICP) analysis for elemental composition and impurity profiling. A Certificate of Analysis (COA) detailing purity, particle size, and other critical parameters is provided with every shipment to ensure traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under inert atmosphere (e.g., argon or nitrogen) for long-term storage to prevent oxidation and moisture absorption. Keep away from strong acids and strong oxidizing agents.
