Quality Control

Our Zinc Chromite is manufactured under controlled conditions to ensure batch-to-batch consistency and high catalytic performance. Quality is verified through a series of analytical tests including X-ray diffraction (XRD) for phase purity, inductively coupled plasma (ICP) for elemental composition, and surface area analysis (BET). Certificates of Analysis (COA) detailing all specifications are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong acids and reducing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
