Quality Control

Our Barium Strontium Tungsten Oxide is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase identification, inductively coupled plasma (ICP) for elemental assay, and laser particle size analysis. A Certificate of Analysis (COA) detailing all specifications 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed in a dry environment to prevent absorption of moisture and caking.
