Quality Control

Our Zirconium Silicide is manufactured under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including X-ray diffraction (XRD) for phase purity and particle size analysis (PSA), to ensure it meets precise compositional and physical specifications. Certificates of Analysis (COA) detailing purity, particle size distribution, and metallic impurity levels are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). The product is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere such as argon or nitrogen for long-term storage to prevent surface oxidation. Keep away from strong acids and strong oxidizing agents.
