Tetragonal-cubic phase boundary in nanocrystalline ZrO2-Y 2O3 solid solutions synthesized by gel-combustion

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 solid solutions, the presence at room temperature of three different phases depending on Y2O3 content, namely two tetragonal form...
