Quality Control

Our Ceramics-Aeium is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive quality assurance, with product specifications tailored to meet the demands of various industrial applications, from technical to high-purity grades. Certificates of Analysis (COA) detailing purity, trace metal analysis, and physical characteristics are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizers. Due to its pyrophoric nature in finely divided forms, appropriate precautions must be taken to prevent ignition. For long-term storage of powder forms, an inert atmosphere (argon or nitrogen) is recommended.
