Quality Control

Our Zinc Sulfide (Hexagonal) is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, crystal phase, and particle size distribution. Certificates of Analysis (COA) detailing key parameters are provided with every shipment. We can support compliance requirements for various industrial standards.

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 product is moisture-sensitive (hygroscopic); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
