| الوصف: | PbTiO3 powders have heen obtained by the sol-gel method using different precursors and catalysts. The whole gelation and crystallisation process was studied by means of XAS spectroscopy at the Ti K-edge and at the Pb Lm-edge. The XANES spectra on the Ti K-edge indicate a marked change of the local environment at 500°C. The local structure around the Ti atoms determined by EXAFS is similar to that ohserved in the pyrochlore phase for annealing temperatures below 500°C . At this temperature both Ti and Pb environments show the occurrence of the Pb-O-Ti bonds indicating the onset of the transformation to the perovskite phase. |
