Microstructural and Electrical Features of Yttrium Stabilised Zirconia with ZnO as Sintering Additive [PDF]

open access: yesMaterials Research, 2016
Adding ZnO reduces sintering temperature of yttria stabilized zirconia. Adding up to 0.5 wt% of ZnO is possible to densify to 8 mol% yttria stabilized zirconia (TZ8Y) to 95% of relative density at 1300 °C, besides, the electrical conductivity increases ...

Adsorption of Water on Yttria-Stabilized Zirconia [PDF]

open access: yesThe Journal of Physical Chemistry C, 2015
Water adsorption on the cubic (111) surface of yttria-stabilized zirconia (YSZ) was investigated using density functional theory calculations. Relaxation of atomic positions away from ideal cubic lattice sites, in particular of the oxygen anion sublattice, is observed on including both phase-stabilizing dopants and water adsorption.

Molecular dynamics simulations of yttria-stabilized zirconia [PDF]

open access: yesChemical Physics Letters, 1995
Oxygen diffusion in the oxygen ionic conductor yttria-stabilized zirconia is investigated by means of the molecular dynamics simulation technique. Oxygen ions migrate by means of a discrete hopping process, mainly between neighbouring tetrahedral sites. Diffusion appears to occur in a short time and a long time regime.

Effect of ion implantation doping on electrical properties of yttria-stabilized zirconia thin films [PDF]

open access: yes, 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,
