Yttria zirconia beads can be used in milling and dispersion of following materials,

  1. Coating, paints, printing and inkjet inks
  2. Pigments and dyes
  3. Pharmaceuticals
  4. Food
  5. Electronic materials and components e.g. CMP slurry, ceramic capacitors,  lithium iron phosphate battery
  6. Chemicals including Agrochemicals e.g. fungicides, insecticides
  7. Minerals e.g. TiO2 GCC and Zircon
  8. Bio-tech (DNA & RNA isolation)
  9. Flow distribution in process technology
  10. Vibro-grinding and polishing of jewelrys, gemstones & aluminum wheels


Main Advantage

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

2. High grinding efficiency.

3. Lower total costs due to longer using life.
