Continuous yttria‐stabilized zirconia fibers
Advanced Materials, 1996Polycrystalline oxide fibers have not yet been exploited to their full potential, perhaps because of difficulties with processability. In the successful new route for the production of continuous yttria‐stabilized zirconia fibers detailed here, ZrO2 particles sols are used as oxide‐forming components.

Journal of the American Ceramic Society, 2002
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.

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.

Palladium-Modified Yttria-Stabilized Zirconia Membranes
Industrial & Engineering Chemistry Research, 2000The reservoir method was applied to produce a continuous palladium (Pd) phase inside the porous yttria-stabilized zirconia (YSZ) membranes. Thin porous YSZ membranes were prepared from YSZ suspension, and the pores were modified with Pd by the liquid-phase impregnation method.

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 ...

Preparation of nanocrystalline yttria-stabilized zirconia
Journal of Materials Research, 1995Nanocrystalline powder with an average crystallite size of 8–12 nm, which was produced by a combustion synthesis process, was used to prepare dense, nanocrystalline articles. Green compacts of high green density were prepared by dry pressing and densified by a fast-firing process.

Conduction mechanism in yttria stabilized zirconia
Physics Letters A, 1967Abstract Analysis of potential distribution curves in 10 Y 2 O 3 : 90 ZrO 2 at 1380°C has shown an electronic hole contribution to the conductivity to have an oxygen partial pressure dependence of p O 2 . This is postulated to arise from the reaction 1 2 O 2 ( gas ) + □ O 2 → O 2- + 2 h .
