White Fused Alumina 3000# Water-Washed Micro Powder White Electrofused Corundum
Characteristics of White Fused Alumina 3000# Water-Washed Micro Powder White Electrofused Corundum:
High purity of aluminum oxide (above 99.5%), resulting in high hardness, strong grinding ability, and high grinding efficiency.
Produced using a water-based process, ensuring more uniform particle size, no large particles, and no scratching of the workpiece surface.
Strong chemical stability, resistant to acids and alkalis, and insoluble in water.
Excellent thermal stability, with wear resistance unaffected at high temperatures.
High whiteness, ensuring no impact on the color of coatings and other products.
Wide range of applications, not only for grinding and polishing but also as an additive material for coatings, ceramics, rubber, plastics, and composite materials.
Product Feature of white fused aluminum oxide powder
The Al2O3 purity is high (99% min). So the hardness & grinding ability is high with good grinding efficiency.
High wear-resistance. Even in high-temperature circumstances, the strength is still excellent.
The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and easy to scatter.
Low oil absorption especially for water-based paint.
Neutral property with PH value around 7-8.
High whiteness. It doesn’t affect the color of paints or coatings adding Al2O3 powder.
Resistant to most corrosive alkali and acid. It doesn’t dissolve in water.
Resistant to high temperature up to 1900 °C.
Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.
