Product Introduction
Our company's White Fused Alumina Micropowder is made from alumina as the main raw material. It is produced by electro-melting at a high temperature of over 2000 degrees Celsius, followed by cooling and crystallization, and then crushing, chemical removal of impurities, and hydraulic/airflow classification to form a fine powder. The particle size is usually in the micron to nanometer range. It is a core raw material for high-end grinding, polishing, and refractory materials. Our White Fused Alumina Micropowder is available in both moisture-based and dry-based forms. The product has extremely high cleanliness and is mainly used in precision grinding and polishing, refractory materials, surface treatment, and other fields. Moreover, our White Fused Alumina Micropowder does not produce any harmful substances, does not contain any toxic impurities, and leaves no residual pollution after use, meeting environmental protection requirements and making it suitable for high-end manufacturing and green production scenarios.

Focus On Products
White Fused Alumina Micropowder is a micron-sized fine powder made from high-purity industrial alumina through high-temperature electrofusion, precision grinding, and multi-stage classification. It boasts an aluminum content exceeding 99%. Our company focuses on product quality, removing impurities through processes such as water washing and acid washing to effectively control quality. The powder exhibits stable chemical composition, strong resistance to acid and alkali corrosion, and does not produce secondary pollution at high temperatures.
Our White Fused Alumina Micropowder exhibits uniform particle size thanks to advanced airflow/hydraulic classification technology. This concentrates the particle size distribution, eliminating large particles and ensuring stable and consistent performance during use, effectively controlling costs and reducing energy consumption.
