Quality Control

Our Silicon Aluminum Oxynitride is produced under stringent quality management systems to ensure batch-to-batch consistency and performance. We employ advanced analytical techniques, including X-ray diffraction (XRD) and scanning electron microscopy (SEM), to verify phase purity, particle size distribution, and morphology. A comprehensive Certificate of Analysis (COA) detailing chemical composition, physical properties, and performance metrics is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored in a cool, dry place with controlled humidity. For long-term stability, store at room temperature (15-25°C) in a desiccated environment. Keep the container tightly sealed when not in use to prevent moisture absorption and contamination.
