Quality Control

Our Barium Ferrite is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Production adheres to relevant ISO standards, and key parameters such as magnetic properties (coercivity, remanence), particle size distribution, and chemical purity are rigorously tested. A Certificate of Analysis (COA) detailing these specifications is provided with every 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). Keep away from sources of ignition and incompatible materials. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption, which can affect performance.
