Quality Control

Our Cerium Aluminum Oxide Nanopowder is manufactured under controlled conditions and undergoes rigorous quality testing. Each batch is analyzed to ensure compliance with stringent specifications for purity, particle size, and phase composition. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment to guarantee traceability and performance consistency for your applications.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent moisture absorption and caking. Keep away from strong acids and strong oxidizing agents.
