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 ...

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.

Journal of Nanoscience and Nanotechnology, 2021
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 [PDF]
Surface and Interface Analysis, 2002 AbstractCleaning 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 surface cleaning ...

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.

The Defect Structure of Yttria Stabilized Zirconia
MRS Proceedings, 1985AbstractWe present results of EXAFS and computer simulation studies of the defect structure of yttria-stabilised zirconia. The results are analysed in terms of dopant-vacancy association models for this phase.

Thermal Expansion of Yttria‐Stabilized Zirconia
Journal of the American Ceramic Society, 1964The thermal expansion of yttria-stabilized zirconia was measured in air and in a high-oxygen atmosphere. Room temperature-to-1000 deg C expansion measurements were made in an automatic recording dilatometer. Measurements above 1000 deg C were made in an oxide induction furnace and the change in length of the specimen was measured with telemicroscopes ...

Ultrasonic attenuation in yttria-stabilized zirconia
Physica B: Condensed Matter, 1999Abstract The acoustic attenuation at 10 MHz in yttria-stabilized zirconia (ZrO2(Y)) was measured at temperatures between 300 and 600 K. The attenuation curve showed a relaxation peak, from which the activation energy was estimated to be 0.7±0.07 eV , in good agreement with the value obtained from dielectric constant of 0.66±0.07 eV ...
