Product Description

Product Description:

Brown Fused Alumina is produced by fusion of bauxite in an electric arc furnace at high temperatures. The brownish coloured product shows high hardness as well as extreme toughness. It is produced by fusion of bauxite in a tilting electric arc furnace at high temperatures. The product shows high temperature resistance, strong erosion resistance, high machinery strength as well as thermal stability. It is a good raw material for manufacturing of shaped refractories.



Less dust

Brown corundum was used as sandblasting surface treatment, because of its relatively high density, so that is less dust in the process of sandblasting. This ensures operator health and safety, at the same time it can improve operator visibility. Compared with slag, in the formation process of slag, cold water or even seawater is used for high temperature cooling, so it form the glass phase structure, with breakability. Because slag is relatively brittle, in the process of grinding, easy to be smashed into small particles. Because the density of slag is relatively small, which results in small slag particles suspended in the air and environmental pollution. Similarly, quartz sand is a very fragile abrasive.

High Efficiency

Brown corundum, under a certain pressure, can quickly impact the surface of the object with a large number of sharp edges, so it is regarded as a very fast spray grinding method. The acceleration and velocity of particles in the air flow are a function of inertance and particle size. The smaller the particle, the easier it is to accelerate and thus produce a higher impact force on the surface of the object, so that resulting in a very high cleaning rate, usually twice as fast as other conventional abrasives.


Brown corundum is very suitable for many fields. Normally, it can be reused several times. If it has not lost its cutting ability after the first time, the number of cycles can be more. Without cutting ability, brown corundum can also be recycled and applied to the construction industry as cement additive.
