Product Details
1. Product Features
· By improving the design of raw materials, we have developed zirconia balls with significantly enhanced resistance to degradation.
· Achieve zirconia spheres with outstanding long-term reliability (wear and degradation resistance)
2. Hydrothermal Treatment + Dispersion Experiment
Conclusion:
Comparison of data between the current series and the rare-earth-free series: The primary reason for the reduced wear in zirconia ball milling without rare earths is the reduction in the monoclinic phase, which leads to improved crack resistance.
3. Comparison
| Current series | Rare-earth-free series | |
| Main ingredient | Zirconium oxide Standard type |
Zirconium oxide Low-temperature sintering type |
| Additive | Yttrium (Rare-earth elements) |
Non-rare earth elements |
| Sintering temperature | 1500 | 1250 |
Conclusion:
· Existing zirconia balls: In the same experiment, wear significantly increased, and surface damage intensified.
· Rare-earth-free zirconia spheres: Even after hydrothermal treatment and dispersion testing, the wear rate remains low and stable, and their appearance shows no significant changes before and after use.
