Quality Control

Our Aluminum Oxide is manufactured under a stringent quality management system to ensure batch-to-batch consistency and compliance with relevant industrial and technical standards. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as purity, particle size distribution, and phase composition. Specifications can be tailored to meet specific requirements for abrasive, refractory, ceramic, or catalytic applications.

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). This material is hygroscopic (moisture-sensitive); keep containers tightly sealed to prevent absorption of atmospheric moisture, which can affect flow properties and performance.
