Abstract
The obtention of a non stoichiometric PMN-PT system has been studied. The influence of different PbZrO3 atmospheres in the sintering process of 3(1 - x)Pb(Mg1/3Nb2/3)O-3 + xPbTiO(3) (PMN-PT) solid solution has been investigated and measured by thermoelectric analysis at 1 kHz. Va lues lower than those for the stoichiometric PMN-PT system have been o btained for T-c. X-ray diffraction (XRD) was performed in the samples for structural analysis and phase identification.
