Quality Control

Our Silicon is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Quality is verified through advanced analytical techniques including ICP-OES/MS for metallic impurities and LECO analysis for oxygen, carbon, and nitrogen content. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment to guarantee compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, strong oxidizers, and halogens. For long-term storage, maintaining a dry, inert atmosphere (e.g., under argon or nitrogen) is recommended to prevent surface oxidation. Recommended storage temperature: 15-25°C.
