The ZrO2-rich region of the ZrO2-MgO system

Journal of Materials Science, 1991
The 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.

Zro2 as a SUPPORT: OXIDATION of CO on CrOx/ZrO2

1991
Summary Supported CrOx catalyst was prepared from Cr(CO) 6 , (NH 4 ) 2 CrO 4 and Cr(NO 3 ) 3 by depositing onto ZrO 2 and SiO 2 . Amount of CrOx deposited was 0.1 - 1.8 mmol/g (0.7 - 13.4 wt% as Cr 2 O 3 ). Catalytic activity was evaluated by the oxidation of CO.

Structure and properties of solid solutions in the systems ZrO2-MgO, ZrO2-CaO, and ZrO2-Y2O3

Refractories, 1983
The phase formation and properties of solid solutions in the ZrO2-MgO, ZrO2-CaO, and ZrO2-Y2O3 systems have been studied over a wide range of concentrations and temperatures (1000–2000°C). The element of a phase diagram has been constructed for the ZrO2-MgO system in the subsolidus region.

Metastable phase formation in the TiO2-ZrO2 and CdO-ZrO2 systems

Solid State Ionics, 1997
Samples 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, 2007
Thin 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.

MOS devices with tetragonal ZrO2 as gate dielectric formed by annealing ZrO2/Ge/ZrO2 laminate

Microelectronic Engineering, 2011
A Ge-stabilized tetragonal ZrO"2 (t-ZrO"2) film with permittivity (@k) of 36.2 was formed by depositing a ZrO"2/Ge/ZrO"2 laminate and a subsequent annealing at 600^oC, which is a more reliable approach to control the incorporated amount of Ge in ZrO"2. On Si substrates, with thin SiON as an interfacial layer, the SiON/t-ZrO"2 gate stack with equivalent

Carbon monoxide hydrogenation over ZrO2 and Cu/ZrO2

Journal of the Chemical Society, Chemical Communications, 1993
Sol–gel-derived ZrO2 with a high surface area (> 250 m2 g–1) is found to be very active in CO hydrogenation and unexpectedly produces propan-2-ol with high selectivity; after incorporation of Cu, a methanol synthesis catalyst is produced not only with a higher activity per unit area than Cu/ZnO, but also with an even lower tendency to produce alkanes ...

Sorption kinetics of cesium on ZrO2 and ZrO2-SiO2-TiO2 microspheres

Radiochimica Acta, 2010
ZrO 2 and ZrO 2 -SiO 2 -TiO 2 (with 1: 1: 1 mol ratio) microspheres have been prepared by the sol-gel method and characterized to study the sorption kinetics of cesium. The effect of pH on the adsorption capacity was determined for both type sorbents and the maximum adsorption percentage of cesium was observed at pH 10.
