Yttria Stabilized Zirconia Bead

Yttrium stabilized zirconia beads are made by using rare earth yttrium oxide as stabilizer, and advanced technology of titration forming and sintering and phasing. The diameter of the tetragonal zirconia crystallites inside the beads is less than 0.5μm, so that the medium has excellent corrosion resistance and wear resistance; the nano-grinding and dispersion of the material becomes a reality after the birth of the uniform and small beads, which is a rod-pin and turbine-type sand grinding. The ideal match for the machine.

Property

1.High specific density : the specific density is 1.6 times more than ordinary zirconia beads.

2.Preventing material from contamination because of its extreme low wear rate.

3.High grinding efficiency.

4.Lower total cost with longer using life.

Recommendations For Grinding Applications

In high energy mills, like pin-mills.

For water-based milling products with low viscosity, low solids - like ink-jet.

In the food industry, for pharmaceutical products and cosmetics.
