Quality Control

Our holmium metal is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Certificates of Analysis (COA) detailing trace metal analysis and physical specifications are provided with each shipment. We can supply material compliant with various purity grades, including 3N (99.9%), 4N (99.99%), and higher, tailored to specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its reactive nature, it is recommended to store under an inert atmosphere such as argon to prevent surface oxidation. Keep away from strong acids and oxidizing agents.
