Quality Control

Our Iron (II) Oxide is produced and tested under stringent quality management systems. We offer various grades, including technical and high-purity, to meet diverse application requirements. Each batch is analyzed to confirm identity, purity, and key physical parameters. A comprehensive Certificate of Analysis (COA) detailing assay results and impurity profiles is provided with every shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality, especially for high-purity grades. Keep away from incompatible materials.
