Quality Control

Our Samarium Boride is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous quality testing, including analysis for purity, particle size distribution, and metallic impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure compliance with your technical 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 under an inert atmosphere or in a desiccator to prevent oxidation and moisture absorption.
