Abstract:
The process of Dy2Zr2O7 (rDy3+/rZr4+ = 1.426) nanocrystals formation and evolution upon calcinations up to 1400 oC has been investigated by means of synchrotron radiation X-ray diffraction (XRD) and Raman spectroscopy. We observed that isothermal calcination of the X-ray amorphous precursor first leads to the formation of oxide nanocrystalline powders with a defect fluorite structure at 800 oC/3 h. The nucleation and growth of pyrochlore phase take place in nanodomains with pyrochlore-type superstructural ordering of cations and anions inside a well crystalline fluorite matrix at > 1200 oC. This is perhaps the first XRD study that reports the presence of a weak pyrochlore-type superstructure in the Dy2Zr2O7.
