Alumina toughened Zirconia (ATZ) or Zirconia Toughened Alumina (ZTA) so-called ATZ or ZTA ceramics have the best mechanical properties within the oxide ceramics and are therefore used for numerous structural components. Their material properties (elect. and therm. properties, stiffness, fracture toughness, internal stresses) are adjusted by the mixing ratio of Al2O3 and ZrO2, the grain sizes of the two components, and the type and quantity of doping elements used to phase-stabilise the ZrO2.
In the case of ATZ/ZTA ceramics, in addition to the composition, the processing, starting with the raw material preparation, shaping, debinding and sintering up to the final machining, has a decisive influence on the material properties, especially on strength and reliability. Microstructural defects must be carefully minimised.
