Grafting of ZrO2 powder and ZrO2 membrane by fluoroalkylsilanes
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2004Abstract The hydrophobic properties of zirconia membrane have been obtained by grafting fluoroalkylsilane on the surface of the ceramic material. Several different grafting experiments were conducted using zirconia powders to determine the optimal conditions of grafting.

The minimum permissible amount of a modifying nanostructured additive in powder compositions has been determined, which makes it possible to carry out the reaction of nitrate-organic synthesis and to provide further nanostructural hardening of ceramics.

Directionally solidified ZrO2-Ta and ZrO2(Y2O3)-Ta composites
Materials Research Bulletin, 1977Abstract Aligned eutectic composites of unstabilized ZrO 2 -Ta and Y 2 O 3 -stabilized ZrO 2 -Ta were grown by direct internal zone melting. Samples with unstabilized ZrO 2 were almost completely crack-free even though the matrix had transformed from the tetragonal to the monoclinic lattice.

Sliding wear of Cr–Al2O3–ZrO2 and Mo–Al2O3–ZrO2 composites
Journal of the European Ceramic Society, 2005The sliding wear behavior of a number of reactively sintered metal-alumina- composites (s-MAC) containing zirconia and pure alumina and yttria-stabilized zirconia (3Y-TZP) reference materials were investigated using a ball-on-disk method. Samples were tested against stainless steel (s/steel) and 3Y-TZP ball-sliders.

ZrO2 and ZrO2SiC particle reinforced MoSi2 matrix composites
Materials Science and Engineering: A, 1992Abstract ZrO 2 MoSi 2 and (ZrO 2 SiC)MoSi 2 composites were fabricated by hot pressing-hot isostatic pressing at 1700 °C. No reactions between ZrO 2 , SiC and MoSi 2 were observed. An amorphous silica glassy phase was present in all composites.

The ZrO2-rich region of the ZrO2-MgO system
Journal of Materials Science, 1991The solubility limits of MgO in tetragonal zirconia were studied by combining the differential thermal analysis data and X-ray disappearing phase method. From these experiments a eutectoid reaction, tetragonal ZrO2 solid solution → monoclinic ZrO2 solid solution + MgO, at 1120±10 °C and 1.6±0.2 mol% MgO was established.

Metastable phase formation in the TiO2-ZrO2 and CdO-ZrO2 systems
Solid State Ionics, 1997Samples of zirconium oxide doped with titanium oxide or cadmium oxide, prepared as a divided state, were examined to investigate the effect of the foreign ions on the zirconia phase transition. Thermal treatments (1173 K in H 2 for TiO 2 -ZrO 2 : 1073 K in air for CdO-ZrO 2 ) caused the incorporation of titanium or cadmium in solid solution in the ...

Study of laser created ZRO2 and hydroxyapatite/ZrO2 films for implantology
Biomolecular Engineering, 2007Thin films of ZrO2 and hydroxyapatite/ZrO2 were created by excimer laser ablation on Ti6Al4V substrates. ZrO2 layers were fabricated in vacuum by KrF laser at various substrate temperatures and hydroxyapatite (HA) layers were fabricated in water vapor ambient by ArF laser and in water vapor/argon ambient by KrF excimer laser.

Catalysis Today, 1998
Abstract In the paper, we review the preparation and the characterization of CrOx/ZrO2, MoOx/ZrO2 and VOx/ZrO2. Catalysts were prepared by various methods (equilibrium adsorption, impregnation or mechanical mixing) and characterized by XRD, XPS, ESR and FTIR techniques. In the paper, we also review the catalytic activity of the ZrO2 supported systems
