"We propose a\u00A0systematic experimental andtheoretical microstructure investigation of a\u00A0variety of zirconia-basednanomaterials, ranging from the nanopowders towards the nanoceramics producedby sintering nanopowders. The project focus on small-sized defects, grainboundaries and nanopores. Pure zirconia, and a variety of binary as well asternary zirconia-based systems in m-, t- or c-phases areinvolved: yttria-stabilized zirconia (YSZ), YSZ doped with Cr, Fe, Mn and somerare earth elements. In addition, a\u00A0study of t- and c-ZrO2stabilized with calcia and magnesia is also planned. Positron annihilationspectroscopy is considerd as the base experimental technique which will becombined with TEM, XRD and XPS measurements. The data obtained within theproject will contribute to explanation and understanding of the materi\u00E1lproperties on a\u00A0microscopic level and to tailoring these materialsaccording to the requirements of specific applications."@en .
