Effect of DC voltage on the microstructure and electrical properties of stabilized-zirconia1
TLDR
In this article, a DC voltage of 8 V at 600°C in air was applied to codoped ZrO2 specimens, and electrons were injected from the cathode into the ZRO2, thus colour centers were formed.About:

Effect of niobia on the defect structure of yttria-stabilized zirconia
TL;DR: In this paper, the defect structure change caused by the additions of Nb2O5 was studied by the positron annihilation technique (PAT), and it was found that the additions can decrease the Vo concentration and increase the (YZrVoY′Zr)x concentration, and possibly decrease the mobility of Vo.

Sintering behavior of Y-doped ZrO2 ceramics: the effect of Al2O3 and Nb2O5 addition
TL;DR: In this paper, the effect of Al 2 O 3 and Nb 2 O 5 addition as the source of +3 and +5 cation dopants in yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) was examined.
Journal ArticleDOI
Feasibility of an Electrochemical Membrane Reactor for the Partial Oxidation of n-Butane to Maleic Anhydride
TL;DR: In this article, the feasibility of n-butane partial oxidation to maleic anhydride (MA) over vanadium phosphorus oxide catalysts in an electrochemical membrane reactor in which an oxygen-ion-conducting electrolyte was used as the membrane was studied.
Journal ArticleDOI
Compatibility analyses of BICUVOX.10 as a cathode in yttria-stabilized zirconia electrolytes for usage in solid oxide fuel cells
TL;DR: In this article, a deleterious interaction between BICUVOX.10 and yttria-stabilized zirconia (YSZ) electrolytes was observed, mainly regarding the yttrium depletion from ZrO2 lattice through reaction with VO2.5.
Dissertation
Performance degradation and recovery of YSZ membrane under sulphuric acid thermal decomposition
TL;DR: In this article, the effect of sulphur dioxide (SO2) present in the cathode feed stream on the performance of a 8 mole% yttria-stabilized zirconia/platinum (8YSZ/Pt) cell was investigated.

Effect of impurities on sintering and conductivity of yttria-stabilized zirconia
TL;DR: In this paper, the effect of low concentrations of Fe2O3, Al 2O3 and Bi2O 3 on the sintering behavior of (ZrO2)083 (YO15)017, made by alkoxide synthesis, has been investigated.
Journal ArticleDOI
Physical origin of the intrinsic grain-boundary resistivity of stabilized-zirconia: Role of the space-charge layers
TL;DR: In this article, the intrinsic grain-boundary resistivity in stabilized-ZrO 2 was considered to originate from the V O depletion in the space-charge layers, and a model was developed.
Journal ArticleDOI
Space charge, elastic field, and dipole contributions to equilibrium solute segregation at interfaces
TL;DR: In this article, the minimum free energy and the equilibrium solute and defect distributions in the grain-boundary region were evaluated. And the authors identified the interaction potentials between solute ions and grain boundaries.

An X-ray photoelectron spectroscopy study of the surface oxidation of zirconium
TL;DR: The early stages of zirconium oxidation have been investigated by X-ray photoelectron spectroscopy (XPS) as mentioned in this paper, where surface oxidation of pure Zr was carried out at room temperature and 10−8 Torr. The film thickness was estimated to be 15±2 A.
