High purity alumina beads

The high purity alumina beads that we developed characterized in excellent abrasion resistance and high purity.

Feature

High purity alumina beads
φ0.2mm

Excellent abrasion resistance

When the high hardness ceramics is ground, abrasion resistance is higher than the zirconia beads.

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.

Excellent corrosion resistance

It is excellent in corrosion resistance to the acid and the alkali.
There is no performance deterioration to the warm water.

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.
