Currently, ceramics are widely used in various industry branches, especially energy, chemistry, and aerospace, as well medicine. Yttria-stabilized zirconia (YSZ) having unique electrical, thermal, mechanical properties is one of the most popular for such applications. In this study, influence sintering temperature yttria percentage on microstructure behavior YSZ have been investigated. Correspo...

Laser machining of the nickel oxide–yttria-stabilized zirconia (NiO–YSZ) composite in Solid Oxide Fuel Cells (SOFCs) may be an effective approach to enlarge electrode–electrolyte interface and improve cell performance. However, laser energy can cause thermal damage surface during machined operation. In this work, microstructure changes collateral caused by pulsed on sintered NiO–YSZ state-of-th...

We employed operando anomalous surface X-ray diffraction to investigate the buried interface between the cathode and the electrolyte of a model solid oxide fuel cell with atomic resolution. The cell was studied under different oxygen pressures at elevated temperatures and polarizations by external potential control. Making use of anomalous X-ray diffraction effects at the Y and Zr K-edges allow...

Gadolinia-doped ceria (GDC) is widely used as an interlayer for preventing the formation of SrZrO3 between yttria-stabilized zirconia (YSZ) electrolyte and lanthanum strontium cobalt iron oxides (LSCF) cathode solid oxide fuel cells (SOFCs). However, diffusion Gd ions to YSZ results in decrease ionic conductivity due Gd2(Zr, Ce)2O7. In present work, we focus on lanthanum-doped (LDC) LSCF cathod...

Epitaxial growth of yttria-stabilized zirconia (YSZ) thin film on through-hole-type porous silicon [tht-PSi(001)] with vertical pores penetrating from the surface to back side Si(001) substrate was achieved. The in-plane and out-of-plane lattice parameters YSZ deposited tht-PSi(001) were, respectively 0.5167 0.5124 nm. Therefore, 0.54 % tensile strain applied film. Also for this work, an all ep...

Abstract Yttria-stabilized zirconia (YSZ) coatings and Al 2 O 3 -YSZ were prepared by atmospheric plasma spraying (APS). Their microstructural changes during thermal cycling investigated via scanning electron microscopy (SEM) equipped with backscatter diffraction (EBSD) X-ray (XRD). It was found that the microstructure of two different, including crystallinity, grain orientation, phase, phase t...

Composite electrodes were prepared by adding 40 wt % La0.8Sr0.2FeO3 (LSF) into porous yttria-stabilized zirconia (YSZ) and their performance was studied as a function of time and calcination temperature. X-ray diffraction (XRD) patterns of the LSF-YSZ composites indicated an expanded lattice parameter after calcination above 1523 K, suggesting that Zr reacted with the LSF to form a Zr-doped per...

Yttria-stabilized zirconia (YSZ)-based thermal barrier coating (TBC) has been integrated with thermographic phosphors through air plasma spray (APS) for in-depth; non-contact temperature sensing. This coating consisted of a thin layer of Dy-doped YSZ (about 40 µm) on the bottom and a regular YSZ layer with a thickness up to 300 µm on top. A measurement system has been established; which include...

Yttria-stabilized zirconia (YSZ) has important electrochemical applications as a fast oxygen ion conductor and is the state-of-the-art electrolyte material for solid oxide fuel/electrolyzer cells. While much attention been paid to conduction, electronic conductivity especially hole carriers are not well understood, yet essential stability, conduction kinetics microstructural evolution in YSZ.
