Yttria Stabilized Zirconia (YSZ) grinding bead is made of yttria stabilized, high purity zirconium oxide powder. The microstructure of our Y-TZP (TZP=tetragonal zirconia polycrystal) grinding beads is characterized by ultra-fine crystalline ceramic particles. Because of this micro structure, our grinding beads has high density, super hardness and excellent fracture toughness, achieving superior grading efficiency compared with other conventional lower density grinding media.


  • Very good roundness and polished surface, extremely high wear resistance with practically no product contamination
  • High fracture toughness, reduced breakage, less maintenance
  • High chemical resistance to all acids, bases, solvents and other corrosive fluids, suitable for wet operations
  • High purity without impurities, suitable for sensitive pharmaceutical, biotechnical, cosmetic and food industrial applications
  • High grinding efficiency with long lifespan
