Quality Control

Our Octaaluminium Barium Tridecaoxide is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing, including X-ray diffraction (XRD) for phase purity and inductively coupled plasma (ICP) analysis for elemental composition, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting purity, particle size distribution, and other critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). The material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
