Quality Control

Our Copper Chromite Black Spinel is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. The product undergoes comprehensive analysis, including assays for catalytic activity, surface area (BET), and metal content. A Certificate of Analysis (COA) documenting purity, physical characteristics, and performance metrics is provided with each shipment to guarantee compliance with your technical requirements.

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 strong acids and strong oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
