Effect of ion implantation doping on electrical properties of yttria-stabilized zirconia thin films [PDF]
, 1992 The change in conductivity of Fe and Ti implanted rf-sputtered layers of yttria-stabilized zirconia (YSZ) was studied as a function of the temperature (400–800°C) and oxygen partial pressure. In an oxidized state and in the temperature range of 400–600°C,

How do the grains slide in fine-grained zirconia polycrystals at high temperature?
, 2007 Degradation of mechanical properties of zirconia polycrystals is hardly discussed in terms of solution-precipitation grain-boundary sliding due to experimental controversies over imaging of intergranular amorphous phases at high and room temperatures ...

Reusable Nanocatalyst: Zirconia and Sulfated Zirconia
International Letters of Chemistry, Physics and Astronomy, 2014 1,5-benzodiazepines have been synthesized by Nano Zirconia and Nano Sulfated Zirconia in solvent free conditions. Synthesis was carried out by conventional as well as microwave method. Benzodiazepines were synthesized by reacting o-phenylenediamine and few ketones in the presence of catalytic amount of Nanoparticles.
