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
