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

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 ...

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.

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 ...

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.

Superplasticity in Zirconia and Yttria Stabilized Zirconia Mixed Powders
Materials Science Forum, 1999Improved elongations were obtained for samples prepared from a novel powder of 2.5 mol % yttria stabilized zirconia when compared to the commercial powders used up to date. The novel powder consists of mixing two phases, zirconia and 6 mol % yttria stabilized zirconia particles to give an average composition of 2.5 mol % yttria.

Deformation mechanisms in yttria-stabilized zirconia
Journal of Materials Science, 1988Yielding behaviour and deformation modes are characterized for single-crystal and polycrystalline yttria-stabilized ZrO2 tested in compression from 23 to 800° C. The plastic flow of single-crystal specimens is shown to be orientation and temperature dependent, and is interpreted in terms of dislocation activity, transformation plasticity, and ...

The dielectric properties of yttria-stabilized zirconia
Materials Letters, 1989Abstract The dielectric properties of yttria-stabilized cubic zirconia were measured over a wide range of frequency (100 to 1 × 10 10 Hz) and temperature (25 to 200°C). The dielectric constant and loss increased with temperature owing to the presence of mobile oxygen vacancies.

Retention of iodine in yttria stabilized zirconia
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1999The diffusion behavior of iodine in yttria stabilized zirconia (YSZ) was investigated as a function of the temperature. Iodine implantation was performed in this cubic solid solution by irradiating material samples with 1 MeV iodine ions. The distribution of iodine was evaluated by using TRIM computer calculation and measured by Rutherford ...

Microwave synthesis of yttria stabilized zirconia
Materials Research Bulletin, 2005Yttria stabilised zirconia (YSZ) nanocrystals, with a mean size between 5 and 10 nm, were prepared by microwave flash synthesis. Flash synthesis was performed in alcoholic solutions of yttrium, zirconium chloride and sodium ethoxide (EtONa) using a microwave autoclave (RAMO system) specially designed by authors.
