YSZ/Ni–YSZ semi-cells shaped by electrophoretic deposition

Journal of the European Ceramic Society, 2007
Abstract The 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, 2020
Abstract 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, 2015
Abstract 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.

Thermal shock life and failure behaviors of La2Zr2O7/YSZ, La2Ce2O7/YSZ and Gd2Zr2O7/YSZ DCL TBCs by EB-PVD

Materials Characterization, 2021
Abstract Double layer ceramic (DCL) thermal barrier coatings (TBCs) have attracted extensive attention due to their high thermal stability under high temperature. The thermal shock life and failure behaviors of DCL TBCs still remain a challenge.

Spray pyrolysis deposition of YSZ and YSZ–Pt composite films

Applied Surface Science, 2005
Abstract 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.

Fabrication and Characteristics of YSZ–YSZ/Al2O3 Double-Layer TBC

Oxidation of Metals, 2011
A novel YSZ–YSZ/Al2O3 (YSZ means 6 wt% yttria partially stabilized zirconia) double-layer thermal barrier coating was fabricated using composite sol–gel and pressure filtration microwave sintering (PFMS) technologies. In this double-layer coating, the top layer was YSZ ceramics with a thickness of about 150 μm and the bottom layer was composed of micro-

Thermophysical Properties of YSZ and Ni-YSZ as a Function of Temperature and Porosity

2008
The thermal diffusivity, heat capacity, thermal conductivity, coefficient of thermal expansion adn elastic properties of Ni-YSZ and YSZ are reported in the temperature interval between 20C and 1000C. Specific heat capacity (Cp)and thermal diffusivity (a) were determined by differential scanning calorimetry (DSC) and by the laser flash method ...

Agglomeration behavior of nickel particles on YSZ and TiO2-doped YSZ electrolytes

Journal of Power Sources, 2012
Abstract Agglomeration behavior of nickel thin films on the yttria stabilized zirconia (YSZ) and TiO 2 doped-YSZ electrolytes under a reducing condition and at solid oxide fuel cell (SOFC) operating temperatures was investigated by scanning electron microscopy (SEM) and scanning probe microscopy (SPM) to clarify whether this method is appropriate to
