Zirconia beads are high-performance ceramic grinding media manufactured from high-purity zirconium oxide (ZrO₂). Renowned for their ultra-high hardness (Mohs hardness ≥8.5), exceptional wear resistance, and chemical inertness, these beads undergo specialized processes such as yttria stabilization (Y₂O₃-ZrO₂) to achieve stable tetragonal or cubic crystal structures. This ensures physical stability even under extreme conditions (e.g., high temperatures, strong acid/alkali environments), delivering a service life 3-5 times longer than conventional alumina beads.
Key Features:
Excellent chemical resistance
