Structural Transformation in Cubic Zirconia

Journal of the American Ceramic Society, 1987
The structure of CaO‐stabilized cubic zirconia has been investigated by X‐ray diffraction at high temperatures and pressures up to 1000°C and ∼35 GPa, using a diamond‐anvil cell interfaced with aYAG laser heating system. At ∼1000°C and 15 GPa, the cubic phase transforms directly into an orthorhombic phase with the PbCl2 structure.

Optical properties of cubic stabilized zirconia

Solid State Communications, 1992
Optical absorption across the fundamental edge and the associated photoluminescence, have been studied in single crystals of yttrium stabilized zirconia (YSZ) of varying yttrium concentration. The results allow discrimination of a region of intrinsic transitions (above 5.2 eV) from a low energy region, where disorder-induced transitions are dominating.

Mechanical loss of cubic zirconia

Journal of Alloys and Compounds, 2000
Cubic zirconia can be stabilized by doping with lower valent oxides such as Y2O3 or CaO. Oxygen vacancies are then created as charge compensating defects. Mechanical loss measurements were performed in the temperature range 300–1600 K using both free decaying (3 Hz, 3 kHz) and forced vibrations (10−2–10 Hz).

Photoactivation of hole centers in cubic stabilized zirconia

Physical Review B, 1996
Photoinduced changes of the concentration of paramagnetic and optical defects have been investigated in cubic stabilized zirconia single crystals by means of electron paramagnetic resonance (EPR). Results are reported confirming the presence of photobleaching of the optical and EPR ${\mathrm{Zr}}^{3+}$ electron centers (T centers) in x-ray-irradiated ...

Stabilization of cubic zirconia by carbon nanotubes

Materials Science and Engineering: A, 2004
Abstract Liquid–liquid two-phase method was used for fabricating Zirconia (ZrO 2 ) nanoparticles, sodium bis(2-ethylhexyl) sulfosuccinite (AOT) surfactant and carbon nanotubes (CNTs) were added into the solution. It has been shown that CNTs acted as the medium during the drying and burning process, which was very important to the formation of ZrO 2 ...

Modelling the Interatomic Potential of Cubic Zirconia

Applied Mechanics and Materials, 2013
Molecular modelling methods were used to investigate the structural and interatomic potential of bulk cubic zirconia. To widen the scope of the expected outcome, GULP and CASTEP software were used based on the concept of minimizing the energy of the crystal structure with respect to atomic coordinates.

Elasto-optical study of stabilized cubic zirconia

Physical Review B, 1995
The piezo-optical coefficients ${\mathrm{\ensuremath{\pi}}}_{11\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}_{12}$ and ${\mathrm{\ensuremath{\pi}}}_{44}$ of cubic yttria-stabilized zirconia are measured as a function of wavelength, temperature, and yttria concentration.

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.
