Quality Control

Our Disilver Tetraborate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure high purity and consistent composition. We provide detailed Certificates of Analysis (COA) upon request, which include key parameters such as assay, heavy metal content, and loss on drying. Our quality commitment ensures the material meets the stringent requirements for electronic grade and research applications.

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 dry environment to prevent caking or degradation. Keep away from strong acids and reducing agents.
