Description of Zirconia Toughened Alumina (ZTA) Nano Powder
ZTA is a superior technical ceramic containing 10-20% volume of ZrO2 in alumina. When pure ZrO2 is added to the alumina and the particles form ZrO2-toughened alumina ceramics, the toughness can be significantly improved when the content is properly added. It was established that ZTA ceramic material is stronger and tougher than regular alumina ceramics. Because of the high price of pure zirconia, ZTA with good toughness is a good choice.

Zirconia Toughened Alumina (ZTA) Nano Powder FAQs
Q1: Why is ZTA preferred for high-strength and high-toughness applications?
A: ZTA is preferred because the addition of zirconia particles to alumina significantly improves its toughness and fracture resistance without compromising its hardness and wear resistance. This makes ZTA suitable for demanding applications where mechanical reliability is critical.
Q2: What particle sizes are available for ZTA nano powder?
A: ZTA nano powder is available in a range of particle sizes, typically from 10 nm to 100 nm for the zirconia particles, depending on the specific application requirements.
Q3: How does the particle size of zirconia affect the performance of ZTA?
A: Smaller zirconia particle sizes provide better dispersion and more effective toughening of the alumina matrix. This leads to enhanced mechanical properties, such as increased toughness and strength. The optimal particle size depends on the specific requirements of the application.
