N2 - Commercial nanopowder of the partially yttrium-stabilized zirconia (ZrO2+3 mol.% Y2O3) was treated by the non-cavitational powerful ultrasonic assistance (PUA). Influence of PUA on the microstructure and phase composition of the powder has been investigated by scanning and transmission electron microscopy. Investigated powder before and after PUA has polycrystalline structure. It was found that TZ-3YS particles after PUA have tetragonal and cubic zirconia phases; some of the particles consist of a mixture of monoclinic, tetragonal and cubic phases, but these particles have substructure with slight disorientation of crystallite fragments.
