Yttria-Stabilized Zirconia Bead Ball as Grinding Media (ZrO2: 94.6%, Y2O3: 5.2%)
Chemshun YSZ beads have high fracture toughness and nice impact resistant that causes no break under high speed impact.
The YSZ beads have 30-50 times higher wear-resistance as glass beads, 5 times higher as Zirconium Silicate beads and 6-8 times higher as Al2O3 beads.
Because of the high density and excellent grinding efficiency of our YSZ beads , they greatly apply to grinding and dispersing high viscosity materials.
