Abstract:	Direct current and alternating current electrical conductivity measurements are used to determine the activation energies for the formation of oxygen vacancies by breakup of bound defect complexes (0.32 eV) and their migration (0.84 eV) at low temperatures (<600°C) in Y₂O₃-fully-stabilized ZrO₂ single crystals. The defect clusters break up between 360° and 450°C.

Keywords:	zirconia ionicconduction electrical conductivity defects activation energy
