Quality Control

Our Tantalum Boride is manufactured under stringent process controls to ensure batch-to-batch consistency and high performance. Quality is verified through advanced analytical techniques including X-ray diffraction (XRD) for phase purity, laser particle size analysis (PSA), and chemical analysis for metallic impurities. A Certificate of Analysis (COA) detailing purity, particle size distribution, and other critical parameters is provided with each shipment.

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 material is stable under normal conditions but should be kept away from strong acids and strong oxidizing agents. For long-term storage, maintaining a low-humidity environment is recommended to prevent any potential surface oxidation.
