Product Description

Product Description

Zirconia balls/beads are fabricated from 3 mol% Y₂O₃-doped partially stabilized zirconia (PSZ), exhibiting exceptional mechanical properties with a room-temperature strength of 980 MPa and fracture toughness of 6 MPa·m¹/². The material demonstrates excellent electrical insulation (volume resistivity >10¹⁵ Ω·cm) and a thermal expansion coefficient (10.0 × 10^-6/K) closely matched to metals, minimizing thermal stress when integrated with metal components. Through high-temperature sintering and phase stabilization, a tetragonal zirconia polycrystalline (Y-TZP) structure is formed, characterized by a uniform and dense microstructure, enabling ultra-low wear rates at the parts-per-million (PPM) level.

 

Application

Zirconia Balls: High-Performance Industrial Grinding Media

Composition & Overview
Zirconia balls are advanced grinding media composed of zirconia-based materials, engineered for ultrafine grinding, precision polishing, sandblasting, and specialized material manufacturing. Their exceptional properties make them indispensable in over 20 industrial sectors, including aerospace, electronic materials, and biomedicine.
 

Core Industrial Applications

1. Ultrafine Grinding & Dispersion

   • Achieve submicron particle sizes with high efficiency, critical for industries requiring narrow particle distribution.

2. Paint & Ink Industry

   • Particle refinement to D90 ≤ 2 μm: Enhances coating glossiness and uniformity while reducing medium loss by 30% (e.g., automotive paints).

3. Electronic Ceramics Processing
