white fused alumina used in industrial ceramic/electronic ceramic

  • Product Feature of White fused alumina used in ceramic line

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 by adding Al2O3 powder.

Resistant to most corrosive alkali and acid. It doesn’t dissolve in water.

Resistant to high temperatures up to 1900 °C.

Good particle size consistency without big size grains. So it prevents scratching on the grinding substrate.
