Fabrication of Porous YSZ from ZnO-YSZ Cermet
Solid State Phenomena, 2007Porous YSZ(8 mol% yttria-stabilized zirconia) was prepared by an acid leaching of ZnO-YSZ composite. The ZnO-YSZ composites were obtained by two different methods, a 1450 °C sintering of the mechanical mixture of ZnO and YSZ powders or a decomposition of Zn(NO3)2 deposited on YSZ and a subsequent sintering.

Effect of alumina additions in YSZ on the microstructure and degradation of the LSM–YSZ interface
Solid State Ionics, 2009The cathode-electrolyte interface in a solid oxide fuel cell is examined to understand why premature delamination is observed in alumina substituted YSZ electrolyte. From XRD. SEM and TEM observations it was concluded that after high temperature sintering a tetragonal (Mn,Al)(3)O(4) forms at the interface, which during prolonged fuel cell operation ...

YSZ/Ni–YSZ semi-cells shaped by electrophoretic deposition
Journal of the European Ceramic Society, 2007The manufacturing of Ni/YSZ self-supported films by aqueous electrophoretic deposition (EPD) for fuel cell applications is reported. The amount and the additives used in an aqueous suspension of Ni and YSZ powders have been optimized to obtain homogeneous and crack-free Ni/YSZ films on graphite substrates.

Porous NiO–YSZ and Ni–YSZ composites fabricated using NiO–YSZ composite nanopowders and WO3 additive
Materials Characterization, 2020Abstract NiO–YSZ composite nanopowders were synthesized through a hydrothermal process without an additional mixing of NiO and YSZ nanopowders. Porous Ni–yttria stabilized zirconia (YSZ) composites, Ni–YSZ composites, with high porosity (25.0–32.8%) were fabricated by reducing NiO-YSZ composites in (94% Ar + 6% H2) gas.

New insights on the role of YSZ in a NiAl2O4/Al2O3–YSZ catalyst
Applied Catalysis A: General, 2015Abstract Yttria stabilized zirconia (YSZ) role as co-support in alumina (Al2O3) supported Al–Ni spinel (NiAl2O4) was investigated from three perspectives: (a) influence on catalyst morphology, (b) influence on catalyst crystalline phases, and (c) role during diesel steam reforming tests.

Spray pyrolysis deposition of YSZ and YSZ–Pt composite films
Applied Surface Science, 2005Abstract In the present paper procedures are described for spray pyrolysis deposition of YSZ films (0.1–30 μm in thickness) with 8 or 15 mole % of YO 1.5 on different substrates. Aqueous or ethylene glycol solutions of Y–Zr-citrates were used as starting material and O 2 as carrier gas.

Effects of Polarization on the Microstructural Changes at the YSZ/Ni-YSZ Interface
ECS Transactions, 2019This study examines the effect of Ni migration near the interface with the electrolyte after fuel cell (SOFC) and electrolysis mode (SOEC) operation on nickel-yttria stabilized zirconia (Ni-YSZ) electrodes. The experimental dataset consists in a series of short-stacks tested under different polarization conditions and durations.

Abstract Hot corrosion is one of the main destructive factors in thermal barrier coatings (TBC s ) which comes as a result of molten salt effect on the coating–gas interface. Hot corrosion behavior of three types of plasma sprayed TBCs was evaluated: (a) usual YSZ (yttria-stabilized zirconia), (b) particle composite of (YSZ + Al 2 O 3 ) and (c ...
