Quality Control

Our Dysprosium(III) Oxide is produced under stringent quality management systems. Each batch undergoes comprehensive analysis to ensure it meets high-purity standards, typically ranging from 99.9% to 99.999% (3N to 5N), depending on the grade. We provide traceable Certificates of Analysis (COA) detailing purity and trace metal content, supporting compliance with global supply chain 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). This material is hygroscopic (moisture-sensitive) and should be kept in a desiccated environment to prevent absorption of atmospheric moisture and carbon dioxide.
