Quality Control

Our Samarium Cobalt Powder (2:7) is manufactured under stringent process controls to ensure batch-to-batch consistency and high magnetic performance. Quality is verified through advanced analytical techniques including X-ray diffraction (XRD) for phase purity, particle size analysis (PSA), and chemical assay for stoichiometric composition. A Certificate of Analysis (COA) detailing magnetic properties (e.g., coercivity, remanence), particle size distribution, and chemical purity is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric and easily oxidized nature, this powder must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and oxidizing agents. The storage temperature should be maintained at room temperature (15-25°C).
