Quality Control

Our Berlinite is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Material specifications are verified through advanced analytical techniques including X-ray diffraction (XRD) for phase identification and spectroscopic methods for elemental purity. A Certificate of Analysis (COA) detailing all relevant parameters is provided with each shipment to guarantee compliance with your technical requirements.

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 material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture uptake, which can affect performance properties.
