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

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.

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 ...

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.
