Highly hardened beads that are highly abrasion resistant and resistant to cracking and chipping!
Features
- Excellent wear resistance
In the case of hardened materials, the wear resistance is superior to that of zirconia beads. - High Purity
These are high-purity alumina beads with a purity of 99.99% or higher.
Contamination of components other than alumina is practically zero, making them suitable for grinding and dispersing electronic material materials that are sensitive to radioisotope contamination. - Excellent corrosion resistance
It has excellent corrosion resistance to acids and alkalis. It also does not deteriorate in hot water, as is the case with zirconia. - Energy-saving dispersion and pulverization
Since the density is almost 2/3 that of zirconia, it can be crushed with 2/3 filling weight. In addition, energy consumption (power consumption) may be saved.
