Equilibrium Analysis of CVD of Yttria-Stabilized Zirconia [PDF]

Journal of The Electrochemical Society, 2005
The calculations performed in this study indicate that efficient deposition of tetragonal yttria-stabilized zirconia (YSZ) by chemical vapor deposition (CVD) is feasible using metal chloride precursors (Zr-Y-C-O-H-Cl system). As reported in the literature, this work demonstrates that high oxygen content is necessary to efficiently utilize metal ...

Superplasticity in Zirconia and Yttria Stabilized Zirconia Mixed Powders

Materials Science Forum, 1999
Improved elongations were obtained for samples prepared from a novel powder of 2.5 mol % yttria stabilized zirconia when compared to the commercial powders used up to date. The novel powder consists of mixing two phases, zirconia and 6 mol % yttria stabilized zirconia particles to give an average composition of 2.5 mol % yttria.

Layered structures of yttria-stabilized zirconia sandwiched between platinum/ yttria-stabilized zirconia composites

Journal of Applied Physics, 2001
Layered structures of cubic yttria-stabilized zirconia (YSZ) sandwiched between two layers of platinum/YSZ composites with the platinum concentration varying between 20 and 55 vol % were prepared. Large double-layer capacitances were obtained due to the presence of large three-dimensional electrode surface areas in the composite layers. The layers were

EXAFS Studies of Yttria Stabilized Zirconia

1984
Yttria stabilized zirconia is a well known solid electrolyte which exhibits fast anion conduction at elevated temperatures. Below 1200° C pure zirconia (ZrO2) is monoclinic, but forms a stabilized cubic phase with the fluorite structure in a solid solution with 9.4 to 24 mole percent Y2O3.

Electro‐Sintering of Yttria‐Stabilized Cubic Zirconia

Journal of the American Ceramic Society, 2013
Electro‐sintering, i.e., electrically enhanced densification without the assistance of Joule heating, has been observed in 70% dense 8 mol% Y2O3‐stabilized ZrO2 ceramics at temperatures well below those for conventional sintering. Remarkably, full density can be obtained without grain growth under a wide range of conditions, including those standard ...

Vanadia reactions with yttria stabilized zirconia

Journal of Applied Physics, 1988
The reaction of vanadia films with yttria stabilized single-crystal cubic and polycrystalline cubic-tetragonal zirconias was studied using Rutherford backscattering (RBS) and x-ray diffraction, with some selected depth profiling studies. Vandium on zirconia readily oxidizes at 500 °C to form vanadia films.

Heat capacity and thermodynamic functions of zirconia and yttria-stabilized zirconia

The Journal of Chemical Thermodynamics, 1999
Abstract Heat capacities of pure zirconia ZrO 2 and 7.76 · 10  − 2 mole fraction yttria-stabilized zirconia ( ZrO 2 ) 0.9224 (Y 2 O 3 ) 7.76·10  − 2 were measured by adiabatic calorimetry at temperatures between 13 K and 300 K. The results were compared and analysed from the standpoint of the effects of yttria doping. The yttria-stabilized zirconia

Low Temperature Degradation of Yttria Stabilized Zirconia

Key Engineering Materials, 2007
This paper explores the effects of dopant content on the aging behavior of tetragonal zirconia polycrystal (TZP). TZP powders with varying Y2O3 content (1.75-3mol%) were synthesized by co-precipitation. After the green body of as-prepared TZP powders being isostatically pressed at 200 MPa and sintered at 14000C for 3 h in air, a range of TZP ceramics ...

Paramagnetic-defect kinetics in yttria-stabilized zirconia

Solid State Ionics, 1991
Abstract The concentration and the thermal stability of paramagnetic defects induced by different treatments in ZrO 2 -12%Y 2 O 3 and ZrO 2 -24%Y 2 O 3 are analyzed by studying their EPR signals. The spectroscopic features of the EPR spectra show that the same types of centers are created in X-ray or UV-light irradiated samples and in samples ...
