Zirconia Toughened Alumina (ZTA) is high purity alumina mixed with zirconia, making a tougher, stronger material.
Zirconia Toughened Alumina:
- Combines the advantages of partially stabilised zirconia (PSZ) and of alumina
- Almost as hard as alumina
- Almost as strong as PSZ
- From 3 to 10 times more abrasion resistant than high purity alumina.
