Quality Control

Our Diantimony Tetrasulphide is produced under strict quality management protocols. Each batch undergoes comprehensive analysis to ensure it meets precise chemical and physical specifications for industrial use. We provide Certificates of Analysis (COA) with key parameters including assay, impurity profiles, and particle size distribution (where applicable) to guarantee batch-to-batch consistency and performance reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials such as strong oxidizers and acids. The product is moisture-sensitive (hygroscopic) and should be kept under conditions that minimize exposure to atmospheric humidity to prevent caking or degradation.
