Product Description

Synthetic Aluminum Oxide Black Fused Alumina 1 - 3 mm 3-5mm for Anti-slip Aggregates
1. Product Description of Synthetic Aluminum Oxide Black Fused Alumina

Synthetic Aluminum Oxide Black is also called as black aluminum oxide or black fused alumina, it contians 

about 60-80% alumina,which is lower than the one of brown and white fused alumina.


While it has the unique  characteristics of moderate hardness,good self-sharpness,strong cutting force,not

easy to burn the treatment and low cost.Then it plays an important role in abrasives and other industries.

3. Which kind of Black Fused Alumina is suitable for anti-slip aggregates?

Black fused alumina section sand:0.4-1mm,1-3mm ect. is more suitable for anti-slip aggregates.

4. Why black fused alumina is used in anti-slip aggregates?

Black fused alumina has the good wear-resistant and anti-slip performance.

It also has the uniform and matte black color,especially for paving the bridge,highway and floors.

Compared with the original aggregates such as brown fused alumina,black silicon carbide,it has the higher

price/performance ratio,its cost is 40% cheaper than the one  of brown fused alumina.

That application for anti-slip aggregates has been used for nearly 10 years in Europe,Hongkong and developed

regions in domestic.

Fosroc Group has been used our black aluminum oxide as anti-slip aggregates for many years.

5. How to use black fused alumina as the anti-slip aggregates?

The common method in domestic is to pave one or more layers of black fused alumina section sand on the

cement roadbed using the resin bond,hereby black fused alumina is used as the surface aggregates.

While the overseas countries use the asphalt as a binder.


6. Other Applications of Fused Aluminium Oxide Black except for Anti-slip Aggregates

  • Bonded abrasives:Resin cutting discs;
  • Coated Abrasives;
