Hydrothermal synthesis of lead titanate and lead zirconate titanate electroceramic particles
Chemical Engineering Communications, 2003Hydrothermal synthesis of two lead-based perovskite powder systems, lead titanate and lead zirconate titanate, was investigated. Phase-pure perovskite lead titanate and lead zirconate titanate with various morphologies have been synthesized by hydrothermal methods at 150° and 175°C, respectively.

Lead zirconate titanate ceramics with aligned crystallite grains
Science, 2023The piezoelectric properties of lead zirconate titanate [Pb(Zr,Ti)O 3 or PZT] ceramics could be enhanced by fabricating textured ceramics that would align the crystal grains along specific orientations. We present a seed-passivated texturing process to fabricate textured PZT ceramics by using newly developed Ba(Zr ...

Refatigue of Ferroelectric Lead Zirconate Titanate
Journal of the American Ceramic Society, 2010Bipolar fatigue of ferroelectric lead zirconate titanate ceramics can be partly recovered by thermal annealing. For samples of initially, intermediately, or highly fatigued state, subsequent refatiguing yields a much more rapid decay in polarization and piezoelectric constant than the initially nonfatigued samples despite very ...

Lead titanate and lead zirconate titanate piezoelectric glass-ceramics
Ferroelectrics, 1994Abstract The crystallization behavior and electrical properties of a piezoelectric glass-ceramic system consisting of lead titanate (PT) or lead zirconate titanate (PZT) in a lead borosilicate matrix is presented. Glass powders of compositions in this system densify at 650°C, and crystallize the ferroelectric PT or PZT phases.

Fatigue of lead titanate and lead zirconate titanate thin films
Physics of the Solid State, 2008The fatigue of lead titanate and lead zirconate titanate ferroelectric thin films, i.e., a change in the polarization as a function of the number of switching cycles in an external electric field, is investigated experimentally. The threshold numbers of switching cycles are determined to be 1010–1011 for the lead titanate films and 109–1010 for the ...

Unipolar fatigue of ferroelectric lead–zirconate–titanate
Journal of the European Ceramic Society, 2003In multilayer actuators the ferroelectric material is known to degrade under bipolar and to some degree under unipolar electric loading. Fatigue effects due to unipolar cycling of a commercial bulk lead–zirconate–titanate up to 4·108 cycles at 2 Ec are demonstrated. Unipolar as well as bipolar polarisation and strain hysteresis loops are measured after

Lead titanate zirconate — based pyroelectric ceramics
Ceramurgia International, 1978Abstract Ceramics with a base composition PbTlxZr1−xO3 (x = 0.07) and modified materials by additions of Nb2O5, Fe2O3 and U3O8 In ≤ 1 wt. % concentration were pressure sintered to near theoretical densities. The effect of these additives on the microstructure and on the dielectric properties are reported and discussed in terms of the A- and O ...

Electrohydrodynamic Deposition of Nanostructured Lead Zirconate Titanate
Journal of Nanoscience and Nanotechnology, 2005The deposition of a propanol-based lead zirconate titanate (PZT) sol using electrohydrodynamic atomization (EHDA) in the stable cone-jet mode was investigated. The droplets generated were deposited onto a copper substrate as a film, which was investigated using X-ray diffraction and scanning electron microscopy.

Processing of porous lead titanate and lead zirconate titanate coatings
Le Journal de Physique IV, 1998Porous lead titanate (PT) and lead zirconate titanate (PZT) coatings were prepared by spin coating alkoxide solutions modified with benzoic acid. Carrying out the spin coating in a humid atmosphere (>30% RH) promoted the formation of porous microstructures. The variations in the chemical structure of the alkoxide and the coating microstructure indicate

Layered lead zirconate titanate and lanthanum-doped lead zirconate titanate ceramic thin films
Journal of Materials Research, 2002The physical layering of sol-gel-derived lead zirconate titanate (PZT) 52/48 and lanthanum-doped PZT (PLZT) 2/52/48 on platinized silicon substrates was investigated to determine if the ferroelectric properties and fatigue resistance could be influenced by different layering sequences.
