Product Description

Good Self-sharpness Synthetic Aluminum Oxide Black Emery to Make Sand Belts Sand Paper

1. Product Description of Synthetic Aluminum Oxide Black Emery

Black Aluminum Oxide belongs to the group of electric corundum,it selects the high alumina bauxite and high

iron bauxite and iron oxide as raw materials,then fused in electric furnace at high temperature,then crushed into

different grain size by roller crusher or barmac crusher.

It is widely used for making abrasives mixed with brown fused alumina in certain ratio,whileIt has the stable

chemical composition and stable crystallization,which offers stable performance compared with the second grade

brown fused alumina.

3. Main Application of Synthetic Aluminum Oxide Black Emery

Black Aluminum Oxide fine grain is widely used for making various coated products such as emery cloth,sand

paper,then converted into final products for polishing purpose,especially for polishing stainless steel products,

black fused alumina is also used for making sponge blocks.


In addition,Black fused alumina is also used in the following applications of

Bonded abrasives:Resin cutting discs;

Polishing stainless steel tableware;

Sandblasting media for surface decontamination,pipeline cleaning,hull-rust and Jean cloth sandblasting;

Anti-skid wear resistant materials;

Polishing wax;

Refractory materials.

4.Why Black Aluminum Oxide is suitbale for making Coated Abrasives?

Black alumium oxide contains 60-80% alumina,then it has moderate hardness,which will generate little heat in

the treatment surface,it will not easy to burn the surface,so when using the coated abrasives made by black fused

alumina to polish the stainless steel, finally it will achieve the black and bule color,which is very close to the essence

of stainless steel,as well as the better visual effect.
