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.Product Description
Activated alumina, there are many micro-paths, so the specific surface is large. It can be used as absorbent, desiccant and catalyst carrier. It is also a kinf of trace water desiccant and the pole-moleculae absorbent, according to the absorbed molecule polarization, the attachment force is strong for water, oxide, acetic acid, alkali ect.Activated alumina defluorinates just as the anion exchange resin, but the selectivity is much strong.The defluorination effect of the activated alumina is good. The capacity is stable. It has high strength,low abrasion, no soften in water, no expansion, no powdery no crack. It can widely used in the deep drying of cracked gas,ethylene and propylene, hydrogen-generation, air seperation, instrument air drying and fluorine treatment for H2O2, alos in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorination.
Features
A white or slightly red particle, ball-shaped or roll-shaped, activated alumina is insoluble in water and organic solvent, soluble in strong acids and alkalis, odorless, tasteless and non-toxic.
Application:
1) Catalyst for recovering sulfur in the petrochemical industry
2) Excellent defluorination agent for drinking water and for recycling alkyl-hydrocarbon in alkylbenzene production
3) Reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry
4) Adsorbent in the production of hydrogen peroxide solution
5) Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product
6) Desiccator and purifying agent.
