Fractal cluster modeling of the fatigue behavior of lead zirconate titanate
(AIP Publishing, 2002-03-01)
The fatigue behavior of lead zirconate titanate ceramics (PZT) has been studied under electrical and mechanical drives. Piezoelectric fatigue was studied using a mechanical method. Under ac mechanical drive, hard and soft ...
Importance of structural irregularity on dielectric loss in (1-x)Pb(Mg1/3Nb2/3)O-3-(x)PbTiO3 crystals
(AIP Publishing, 2002-06-01)
The dielectric properties of (1-x)Pb(Mg1/3Nb2/3)O-3-(x)PbTiO3 (PMN-PT) crystals have been investigated over a temperature range of 4 to 450 K at various frequencies. At low temperatures, an unusual frequency dependent ...
Enhanced piezoelectricity and nature of electric-field induced structural phase transformation in textured lead-free piezoelectric Na0.5Bi0.5TiO3-BaTiO3 ceramics
(AIP Publishing, 2012-04-01)
This letter provides a comparative description of the properties of textured and randomly oriented poly-crystalline lead-free piezoelectric 0.93(Na0.5Bi0.5TiO3)-0.07BaTiO(3) (NBT-BT) ceramics. A high longitudinal piezoelectric ...
Electromechanical behavior of 001 -textured Pb(Mg1/3Nb2/3)O-3-PbTiO3 ceramics
(AIP Publishing, 2012-05-01)
-textured Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PMN-PT) ceramics were synthesized by using templated grain growth method. Significantly high  texture degree corresponding to 0.98 Lotgering factor was achieved at 1 vol. % ...
Giant energy density in 001 -textured Pb(Mg1/3Nb2/3)O-3-PbZrO3-PbTiO3 piezoelectric ceramics
(AIP Publishing, 2013-01-01)
Pb(Zr,Ti)O-3 (PZT) based compositions have been challenging to texture or grow in a single crystal form due to the incongruent melting point of ZrO2. Here we demonstrate the method for achieving 90% textured PZT-based ...
