Quality Control

Our Sodium Silicide is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase identification and titration for active content. A Certificate of Analysis (COA) detailing purity, particle size, and metallic impurities is provided with each shipment to meet the stringent requirements of our industrial and research partners.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 15-25°C. Keep away from moisture, water, and oxidizing agents.
