Quality Control

Our Aluminum Cobalt Oxide is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase identification and inductively coupled plasma (ICP) for elemental assay. Certificates of Analysis (COA) detailing purity, particle size distribution, and other critical parameters are provided with every shipment 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). Keep away from incompatible materials such as strong acids. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
