Synthesis of stable nanocrystalline cubic zirconia

Materials Research Bulletin, 2000
Abstract Nanocrystalline pure cubic zirconia was prepared by precipitation in polymer matrix. The average particle size obtained by this method was smaller than that obtained by aqueous coprecipitation. X-ray diffraction showed that the cubic form is stable in air up to 1173 K and partially stable in an inert argon atmosphere up to 1273 K.

Radiation damage in cubic-stabilized zirconia

Journal of Nuclear Materials, 2013
Abstract Cubic yttria-stabilized zirconia (YSZ) can be used for nuclear applications as an inert matrix for actinide immobilization or transmutation. Indeed, the large amount of native oxygen vacancies leads to a high radiation tolerance of this material owing to defect recombination occurring in the atomic displacement cascades induced by fast ...

Absorption Spectrum of Er3 + Ions in Cubic Zirconia

Physica Status Solidi (a), 1972
Yttria-stabilized zirconia crystals doped with Er3+ ions were prepared from the melt using a large solar furnace. In order to investigate the oxygen ion coordination around Y3+ ion using Er3+ ion as a probe, the absorption spectra of the crystals were measured in the spectral region 30000 to 4000 cm−1.

Temperature dependence of Raman scattering in stabilized cubic zirconia

Physical Review B, 1995
The temperature dependence of Raman spectra of cubic yttria-stabilized zirconia (YSZ) for three yttria concentrations (10, 15, and 20 wt %) is investigated in the range 40--1470 K. The variation of the spectra with temperature implies that first-order scattering (one-phonon processes) is dominant in this material, providing further evidence that the ...

Defect-induced hyper-Raman spectra in cubic zirconia

Physical Review B, 1986
Hyper-Raman scattering of cubic zirconia and ${\mathrm{CaF}}_{2}$ is measured at room temperature. For a ${\mathrm{CaF}}_{2}$ crystal, the frequencies of the TO and LO modes with ${T}_{1u}$ symmetry are determined to be 260 and 480 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$, which are in good accord with the results of infrared measurements.

Three-dimensional microstructural characterization of porous cubic zirconia

Micron, 2015
A set of cubic zirconia samples were investigated using 3-dimensional electron backscatter diffraction (3D EBSD) to analyze the grain structure, grain boundary networks and pore morphology. 3D EBSD is a variation of conventional EBSD, whereby a focused ion beam (FIB) is used in a dual beam scanning electron microscope (SEM) i.e.

Translucency of IPS e.max and cubic zirconia monolithic crowns

The Journal of Prosthetic Dentistry, 2018
Although several monolithic zirconia ceramics have recently been introduced, the need for improved optical properties remains. The newest cubic-zirconia has been claimed to have optimal translucency characteristics for esthetic restorations.This in vitro study evaluated the optical properties of novel cubic ultratranslucent (UT) and supertranslucent ...

Phase stabilization in nitrogen-implanted nanocrystalline cubic zirconia

Physical Chemistry Chemical Physics, 2011
The phase stability of nanocrystallites with metastable crystal structures under ambient conditions is usually attributed to their small grain size. It remains a challenging problem to maintain such phase integrity of these nanomaterials when their crystallite sizes become larger.

Stabilization of Cubic Zirconia by Aluminum Nitride

Journal of the American Ceramic Society, 1989
Cubic ZrO 2 is stabilized at room temperature by the addition of AIN. The percentage of c‐ZrO 2 in the mixture of c‐ZrO 2 and m‐ZrO 2 increases linearly with the addition of
