Zirconia Toughened Alumina

Zirconia toughened alumina is manufactured using stress induced transformation of fine tetragonal zirconia particles. This uniform particle size and distribution results in extreme strength, toughness and resistance to thermal shock; properties which make ZTA suitable for a wide range of applications and environments.

Typically, zirconia Toughened Alumina will have a zirconia content of 10%-20%. Depending upon this content percentage, the properties of the ceramic can be adapted to suit the application in question. ZTA is generally regarded to be an intermediate between alumina and zirconia and is accordingly priced, frequently making zirconia toughened alumina a high value, cost effective solution.
