Hydrothermal synthesis of lead titanate and lead zirconate titanate electroceramic particles

Chemical Engineering Communications, 2003
Hydrothermal 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.

Processing of porous lead titanate and lead zirconate titanate coatings

Le Journal de Physique IV, 1998
Porous 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

Lead zirconate titanate ceramics with aligned crystallite grains

Science, 2023
The 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 ...

Fatigue anisotropy in lead-zirconate-titanate

Journal of the European Ceramic Society, 2004
Bipolar fatigue in bulk lead-zirconate-titanate ceramics is known to induce a severe loss of switchable polarization and strong asymmetries of strain hysteresis in cycling direction. An investigation into the transverse functional dependencies is conducted here. The polarization hysteresis perpendicular to the cycling direction only loses 35% amplitude

Refatigue of Ferroelectric Lead Zirconate Titanate

Journal of the American Ceramic Society, 2010
Bipolar 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 ...

Electrohydrodynamic Deposition of Nanostructured Lead Zirconate Titanate

Journal of Nanoscience and Nanotechnology, 2005
The 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.

Lead titanate and lead zirconate titanate piezoelectric glass-ceramics

Ferroelectrics, 1994
Abstract 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.
