Introduction to ZTA (Zirconia Toughened Alumina): Properties, Benefits, Types, and Applications
ZTA (Zirconia Toughened Alumina) is a ceramic material primarily composed of alumina, with 10% or 20% zirconia added and sintered. Compared to pure alumina ceramics, ZTA offers approximately twice the strength and stiffness. When compared to zirconia ceramics, ZTA has a lower thermal expansion coefficient, higher thermal conductivity, and better resistance to thermal shock. By combining the strengths of both alumina and zirconia, ZTA stands out as a high-performance ceramic material.
Key Advantages of ZTA Ceramics
- Balances performance characteristics between alumina and zirconia ceramics.
- Costs significantly less than zirconia ceramics while being slightly more expensive than alumina ceramics, making it a cost-effective choice.
Typical Applications of ZTA
- Artificial joints
- Pump components
- Grinding media
