1) Feature & Application
1.Excellent abrasion resistance
When the high hardness ceramics is ground, abrasion resistance is higher than the zirconia beads.
2.High purity
The purity of the alumina beads is 99.99% or more.
When grinding, no contamination other than alumina.
It is suitable for grinding and dispersion of the electronic material that dislikes mixing the radioisotope.
3.Excellent corrosion resistance
It is excellent in corrosion resistance to the acid and the alkali.
There is no performance deterioration to the warm water.
4.Energy saving of grinding and dispersion
The density of alumina is 2/3 of the zirconia, and the filling weight to the mill is 2/3.
In addition, there is a possibility that the consumption energy when grinding can be decreased.

Because of its high strength, high hardness, high wear resistance, large ratio, small size, high temperature resistance, corrosion resistance, no pollution and other excellent characteristics, high aluminum ball is widely used in different types of ceramics, porcelain glaze, glass, chemical and other factories of thick and hard material finishing and deep processing.
High alumina ceramic balls are widely used as catalyst carrier fillers in the world because of their excellent stability and reliability. Produced from high quality alumina powder, they have very good stability, high mechanical strength and thermal shock resistance, which makes them ideal for supporting all types of catalysts.
