The effect of the yttria-stabilized zirconia (YSZ) nanoparticle loading in an electro-less bath was considered as one of the vital synthesis variables for control Ni content and microstructure of prepared nanocomposite particles, which are two crucial factors to achieving high-performance SOFC anode. Nanocomposite particles were prepared using a simple

Subsurface segregation of yttria in yttria stabilized zirconia
Journal of Applied Physics, 2002The segregation behavior in 3 and 10 mol % polycrystalline yttria stabilized zirconia (YSZ), calcined at temperatures ranging from 300 to 1600 °C, is characterized using low-energy ion scattering (LEIS). In order to be able to separate the Y and Zr LEIS signals, YSZ samples have been prepared using isotopically enriched Z94rO0 instead of natural ...

Phase stability of scandia–yttria-stabilized zirconia TBCs
Surface and Coatings Technology, 1998Abstract The evolution in phase composition resulting from 1400°C ageing of ZrO 2 samples stabilized by ∼4–7 mol.% each of Y 2 O 3 (YSZ), Sc 2 O 3 (ScSZ), or a mixture of Sc 2 O 3 –Y 2 O 3 (SYSZ) was studied by synchrotron radiation X-ray diffraction (SR XRD) using whole powder pattern fitting (WPPF), a recently proposed Rietveld-based method for

Refractive index of cubic zirconia stabilized with yttria
Applied Optics, 1982The optical transmission and indices of refraction for the cubic isomorph of ZrO(2) stabilized with 12.0-mol % Y(2)O(3) were measured at various temperatures and for a range of wavelengths from 0.36 to 5.1 microm. Index data to +/-5 x 10(-5) were fitted to a three-term Sellmeier equation. The value of N(D) = 2.15847.

Abstract Bulk and grain boundary diffusion of Nb5+ cations in yttria-stabilized zirconia (YSZ, 8 mol% Y2O3–92 mol% ZrO2) and in titania-doped yttria-stabilized zirconia (Ti–YSZ, 5 mol% TiO2–8 mol% Y2O3–87 mol% ZrO2) was studied in air in the temperature range from 900 to 1300 °C. Experiments were performed in the B-type kinetic region.

The low bonding strength between hydroxyapatite (HA) and the metal substrate interface of plasma‐sprayed HA coating has been a point of potential weakness in its application as a biomedical prosthesis. In the present study, yttria‐stabilized (8 wt%) zirconia (YSZ) has been used to enhance the mechanical properties of HA coatings.

Surface cleaning and characterization of yttria‐stabilized zirconia
Surface and Interface Analysis, 2002Abstract Cleaning substrate surfaces and checking the effectiveness of the cleaning method are two very important aspects of reliable surface analysis. The absence of a cleaning process leading to an yttria‐stabilized zirconia (YSZ) surface that is free of contaminants and of unchanged structure has inspired us to investigate a new ...

Threshold displacement energy in yttria‐stabilized zirconia
physica status solidi c, 2007AbstractWe have studied the color center production in yttria‐stabilized zirconia single crystals (i.e. ZrO2: Y with 9.5 mol% Y2O3) with the (100) orientation, by electron irradiations at energies ranging between 1.0 and 2.5 MeV. Electron paramagnetic resonance (EPR) measurements show that three paramagnetic centers are stable at room‐temperature: i ...

X-ray photoelectron spectroscopic studies on yttria, zirconia, and yttria-stabilized zirconia
Journal of Applied Physics, 1991Surfaces of yttria, zirconia, and yttria-stabilized zirconia were studied using x-ray photoelectron spectroscopy. An almost threefold increase in the surface yttrium concentration was observed in the yttria-stabilized zirconia samples. The core level binding energies of yttrium, zirconium, and oxygen ions in yttria-stabilized zirconia showed chemical ...
