Abstract
In the paper the elaboration of Pb(Mg1/3Nb2/3)O3 � PbTiO3 with a perovskite structure by using a variant of the columbite method is presented. Very often, in the elaboration process of this compound a secondary pyrochlore (Pb3Nb4O13) phase is obtained, due both to its high stability in comparison with the perovskite and to the evaporation of the lead oxide (PbO) during the processing. A new preparation variant has been used in order to avoid the formation of the secondary compound, namely a three step columbite method. The best sintering conditions were established by studying the densification of the material by scanning electronic microscopy. The crystalline perovskite phase was put into evidence by using X-Ray diffraction. The results showed the formation of the pyrochlore free Pb(Mg1/3Nb2/3)O3 � PbTiO3 (PMN-PT) ceramics in all the samples sintered at 1100 0C.
