The 99.99 type alumina ceramic beads are made of the finest ground raw materials. The structure of the beads is made dense by a sintering process. The beads have a matte surface, high roundness, and very good mechanical properties. Because of the high roundness of the spheres, the wide range of size selection, the selection of the right size beads according to the size of the product to be ground and the inclusion and matching of other properties of the ground product, the grinding rate can be increased to reduce production costs. High-purity alumina porcelain balls are composed of micron-level polycrystals, with good wear resistance,  high hardness, stable chemical properties and strong corrosion resistance to acids and alkalis. Also it can solve the pollution problem of other harmful impurities introduced due to the lack of purity of high alumina alumina balls.

1) Long life, high strength, high hardness, stable performance

 High-purity alumina ball has uniform and meticulous alumina crystalline organization, high wear resistance of high-purity aluminum ball, not easy to break, long life.

 2）High purity (99.99%)

 High purity alumina ball has very low content of radioactive isotopes, so it can be used for applications with restrictions on radioactive elements.

 3）Resistant to acid and alkali corrosion, resistant to warm water corrosion

 High purity alumina ball has strong corrosion resistance to acid and alkali, etc. In the grinding high alumina alumina ball in the crushing accompanied by the temperature rise of the slurry inside the grinding irrigation, wear resistance will have a tendency to drop, but high purity alumina ball will not be affected by such, high purity alumina can withstand a wider range of temperatures.

 4）Energy saving

 The density of alumina is 2/3 of that of zirconia, and the filling weight only needs to reach 2/3, which can reduce the power consumed during crushing and realize energy saving.
