99.99% High Purity Alumina Grinding Balls

Pure alumina ceramic ball: AL2O3 content ≥99.99%, true specific gravity 3.93g/cm3, Mohs hardness 8.5-9

The high-purity alumina ball series has excellent wear resistance and a purity of 99.99%. The high-purity alumina ceramic balls are composed of micron-level polycrystals and have good wear resistance; they have high hardness; they have stable chemical properties and are resistant to acids and alkali. Strong corrosion resistance; at the same time, it can solve the pollution problem of other harmful impurities introduced due to insufficient purity of high-alumina alumina balls.

Application areas:

It is suitable for grinding and catalytic support in chemical, ceramic, electronic materials, magnetic materials, special cement, paint, medicine, coatings, refractory materials, mining and other industries.

Product features:

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

High-purity alumina balls have a uniform and fine alumina crystal structure. High-purity aluminum balls have high wear resistance, are not easy to break, and have a long service life.

2) High purity (99.99%)

High-purity alumina spheres contain very high levels of radioactive isotopes, so they can be used in applications where radioactive elements are restricted.

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

High-purity alumina balls have strong corrosion resistance to acids and alkalis. During grinding, when the high-alumina alumina balls are crushed, the temperature of the slurry in the grinding pot rises, and the wear resistance tends to decrease. However, high Pure alumina balls are not affected by this, and high-purity alumina can withstand a wider temperature range.

4) Energy saving

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