Zirconia Toughened Alumina Ceramic

Zirconia Toughened Alumina (ZTA) is high purity alumina mixed with zirconia, making a tougher, stronger material.

Zirconia Toughened Alumina:

Combines the advantages of partially stable 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.
