Phase stability of scandia–yttria-stabilized zirconia TBCs

Surface and Coatings Technology, 1998
Abstract 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

EXAFS Studies of Yttria Stabilized Zirconia

1984
Yttria stabilized zirconia is a well known solid electrolyte which exhibits fast anion conduction at elevated temperatures. Below 1200° C pure zirconia (ZrO2) is monoclinic, but forms a stabilized cubic phase with the fluorite structure in a solid solution with 9.4 to 24 mole percent Y2O3.

Raman Investigation of the Nitridation of Yttria‐Stabilized Tetragonal Zirconia

Journal of the American Ceramic Society, 2003
Raman spectroscopy has been used to obtain Raman spectra of yttria‐stabilized tetragonal zirconia subject to surface nitridation induced by contact with zirconium nitride. Raman spectra recorded from regions at increasing distance from the source of nitridation have been used to obtain diffusion profiles from samples treated at ...

Spectroscopic investigation of the electronic structure of yttria-stabilized zirconia

Physical Review Materials, 2018
The electronic structure and optical properties of yttria-stabilized zirconia are investigated as a function of the yttria content using multiple experimental and theoretical methods, including electron energy-loss spectroscopy, Kramers-Kronig analysis to obtain the optical parameters, photoelectron spectroscopy, and density functional theory.

Nanoindentation examination of yttria-stabilized zirconia (YSZ) crystal

Journal of Alloys and Compounds, 2007
Abstract The paper clarifies the specific mechanical properties of single crystal YSZ through applying the nanoindentation examination and the finite element analysis with theoretical ultrasonic measurements. The obtained results demonstrate that the lack of precise determination of the Poisson's ratio results in the significant discrepancy between ...

Yttria-stabilized Zirconia with beige colour

2018
Zirconia is a very versatile advanced ceramic that offers an interesting combination of thermal, chemical, electrical, mechanical and optical properties which are uncommon to find in ceramic materials and therefore is used in several applications. INNOVNANO is one of the main Zirconia powders suppliers in the market with potential clients for beige YSZ
