Product Description
Zirconia Grinding Ceramic Balls/Beads: Technical Specifications and Performance Characteristics
Material Composition & Structure
- Base Material: 3mol% Y2O3 partially stabilized zirconia (PSZ)
- Microstructure: Tetragonal zirconia polycrystals (Y-TZP) formed via high-temperature sintering and phase stabilization, featuring uniform density and sub-micron grain structure
- Key Properties:
- Mechanical strength: 980 MPa (room temperature)
- Fracture toughness: 6 MPa·m¹/²
- Electrical insulation: Volume resistivity >10¹5 Ω·cm
- Thermal expansion: 10.0×10-6/K (metal-compatible, minimizes thermal stress)
Performance Advantages
-
Wear Resistance
40% lower wear rate vs. steel balls under high-speed grinding - Vickers hardness >1200 kgf/mm²
- Elastic modulus: 200 GPa
- Achieves PPM-level wear rates
-
Impact Resistance
Crushing strength >150 kgf - Withstands high-speed sand mill operation without fragmentation
-
Density & Energy Transfer
Density 6.0 g/cm³ enhances kinetic energy for viscous material grinding -
Surface Properties
Pearl-lustered surface reduces material adhesion - Maintains uniform wear morphology post-use
