摘      要：A series of(100−x)Pb(Mg_(1/3)Nb_(2/3))O_(3−x)PbTiO_(3)(PMN−xPT,x=24,25,26)ceramics were prepared by solid-state reaction technique using MgNb_(2)O_(6)*** results of the detailed characterizations reveal that the content of PT has negligible influence on the grain size,and all samples possess the perovskite *** the PT content increases,the samples changed from the normal ferroelectric phase to the ergodic relaxor state at room *** a result,PMN-xPT ceramics are endowed with electro-strain of 0.08%at a relatively low electric field of 2 kV/mm,and effective piezoelectric coefficient of 320 pm/V was ***,the PMN-xPT ceramics have exceptional pyroelectric performance,exhibiting a high pyroelectric coef-ficient p~5.5-6.3×10^(−8)C·cm^(−2)·K^(−1).This study demonstrates the great potential of PMN-xPT for piezoelectric and pyroelectric device applications.
