We have investigated the crystal structures and phase transitions of nanocrystalline ZrO2− 1
to− 13 mol% Sc2O3 by synchrotron X-ray powder diffraction and Raman spectroscopy …

ZrO2-10, 12 and 14 mol% Sc2O3 nanopowders were prepared by using a nitrate-lysine gel-
combustion synthesis. These materials were studied by synchrotron X-ray powder diffraction …

The local atomic structures around the Zr atom of pure (undoped) ZrO2 nanopowders with
different average crystallite sizes, ranging from 7 to 40 nm, have been investigated. The …

Zirconia-based materials are widely investigated and used as electrolytes in solid-oxide fuel
cells, oxygen sensors and electrochemical devices. These materials present polymorphism …

By means of synchrotron X-ray powder diffraction (SXPD) and Raman spectroscopy, we
have detected, in a series of nanocrystalline and compositionally homogeneous ZrO2–Y2O3 …

The role of Y-, Ca-and Ce-doping of cubic zirconia (c-ZrO2)(111) surface on its acidity,
basicity and the interplay between surface acid–base pairs is investigated by computational …

In this paper, we report a study of the effect on the powder morphology of zirconia based
solid solutions of several parameters of the synthesis by gel-combustion routes, such as fuel …

The metal structural environments in macroscale and nanoscale Zn x Ni1–x O solid
solutions were examined using X-ray diffraction (XRD), X-ray absorption spectroscopy …

Samples of ZrO 2 were prepared by different procedures in order to figure out the most
active tetragonal phase. Preparation methods differed in factors such as pH, precipitation …
