Quality Control

Our Silicic Acid, Barium Salt is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency and meets the high-purity standards required for industrial and technical applications. A Certificate of Analysis (COA) detailing key parameters such as assay, heavy metal content, and particle size distribution is available for every shipment upon request.

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); keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect flow properties and reactivity.
