Product Description

White Fused Alumina Micropowder is a high-purity abrasive material produced from fused alumina that has been carefully milled and precisely classified into ultra-fine particle sizes. With α-Al₂O₃ as the main crystalline phase, the material delivers outstanding hardness, excellent cutting ability, and a stable performance profile suited for fine processing applications.

Due to its clean surface and controlled particle size distribution, this micropowder ensures smooth polishing results, uniform finishes, and reliable consistency in use. The product also maintains strong chemical stability and thermal resistance, making it an ideal ingredient for precision polishing, advanced ceramics, electronic components, coatings, and high-grade refractory formulations.

   Core Features

• High Hardness & Strong Cutting Ability: Provides efficient material removal and stable grinding performance for precision processing.

• Excellent Self-Sharpening: Maintains cutting performance over time, ensuring consistent polishing and finishing results.

• Uniform Particle Size Distribution: Ensures smooth surfaces, controlled finishes, and reliable behavior in fine-processing applications.

• High Purity & Chemical Stability: Low impurity content leads to cleaner processing, better compatibility, and improved product performance.

• Thermal & Mechanical Stability: Performs reliably under high temperatures and rapid thermal changes, suitable for advanced ceramics and refractory use.

• Clean Surface After Washing Treatment: Acid-washing and water-washing provide better cleanliness and enhance dispersion and consistency.
