Quality Control

Our Lanthanum Dodecaboride is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Production is supported by advanced analytical techniques including X-ray diffraction (XRD) for phase identification and inductively coupled plasma (ICP) analysis for elemental purity. A comprehensive Certificate of Analysis (COA) detailing purity, particle size distribution, and other critical parameters is provided with each shipment to guarantee compliance with your technical specifications.

Storage

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