摘要：

The elaboration of bulk (1-x)Pb(Mg1/3Nb2/3)-xPbTiO(3) by using the columbite method is presented. The main aim of the processing was to avoid the formation of an unwanted pyrochlore phase. Optimized sintering temperatures have been chosen in correlation with the densification evolution. Samples with the PMN/PT ratio of 1.0/0.0, 0.9/0.1 and 0.65/0.35 have been processed; X-Ray diffraction and scanning electronic microscopy investigation are presented. The results showing the formation of pyrochlore-free structure in all the investigated samples at sintering temperatures around 1,100 degrees C.
