Quality Control

Our Aluminum Oxide Hydroxide is manufactured under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure it meets precise specifications for phase purity, particle size distribution, and chemical composition. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
