Quality Control

Our Tmm(M)-Si3N4 is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, particle size distribution, and chemical composition. Certificates of Analysis (COA) detailing key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at controlled room temperature (15-25°C). The container must be kept tightly sealed in a dry environment to prevent degradation from atmospheric moisture.
