Alumina Toughened Zirconia (ATZ) grinding bead is produced by special dropping and rolling method, sintered at high temperature. TC-ATZ80 has a medium density between density of Y-TZP95 and zirconium silicate bead.


  • Good roundness and polished surface, extremely high wear resistance
  • High chemical resistance to all acids, bases, solvents
  • Good performance-price ratio, greatly reduce production costs, and increase grinding efficiency


  • non-metal mining such as Kaolin, CaCO3 and silica
  • Paint, printing ink, pigment etc
  • Metal mining such as gold, copper and zinc & lead etc.
  • Powder such as titanium pigment, alumina powder, zircon sand, silicon powder
