Aluminum oxide micro powder

1. Product Overview

Aluminum Oxide Micro Powder (White Fused Alumina Micro Powder) is a high-purity, sharp-edged abrasive produced from high-quality alumina powder in an electric arc furnace at temperatures above 2000℃. At Henan Yumo New Materials, we use multi-stage sieving and water-suspension processes to ensure ultra-precise particle size distribution.

  • Purity: Al2O3 ≥ 99.5%

  • Hardness: 9.0 Mohs (Aggressive cutting)

  • Color: Pure White (No contamination)

  • Key Feature: Advanced Moisture Control (≤0.1%)

3. Core Advantages

⚫ Black Silicon Carbide

A. Precise Particle Size Distribution (PSD)

We use laser diffraction testing to ensure the grit size is uniform. This prevents random scratches on high-precision surfaces, making it ideal for the semiconductor and optical industries.

B. Advanced Moisture Control & Drying

Unlike standard micro powders, our materials undergo a specialized drying process.

  • Result: Ultra-low moisture ($\le 0.1\%$), ensuring no clumping in Jumbo Bags and easy dispersion in slurries.

C. High Self-Sharpening Ability

The angular crystals continuously break during the grinding process to reveal new, sharp edges, maintaining a high cutting rate throughout the operation.

D. Acid-Washed & Suspension Treated

To ensure the highest purity, our micro powder is acid-washed to remove iron and other impurities, ensuring it is chemically inert and non-reactive with your workpieces.

Packaging & Shipping

We can provide 1MT/25Kg woven plastic bags and 25Kg paper bags. And ton bag packaging.

All of our abrasive products are carefully processed during storage and transportation to maintain their quality in their original state.
