Quality Control

Our Scandium Hexaboride is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through advanced analytical techniques including X-ray diffraction (XRD) for phase purity and inductively coupled plasma (ICP) analysis for elemental composition. A Certificate of Analysis (COA) detailing purity, particle size distribution, and other critical parameters is provided with every 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). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere such as argon or nitrogen for long-term storage to prevent oxidation and moisture absorption. Keep away from strong acids and strong oxidizing agents.
