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 ...

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.

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

Journal of Thermal Analysis and Calorimetry, 2004
Crystalline PbTiO3 was obtained through the thermal decomposition of 8-hydroxyquinolinate of lead(II) and that of titanium(IV), which was monitored by TG/DTG/DTA under different atmospheric conditions and with varying heating rates. The compound was prepared from adding 8-hydroxyquinoline solution in the solution of metallic ions Pb(II):Ti(IV) (1:1 ...

Journal of the American Ceramic Society, 1998
Lead titanate (PT) powders of nanometer particle sizes were prepared using a sol‐gel process. The PT gel was annealed at various temperatures to produce powders with different particle sizes. X‐ray diffractometry (XRD), thermogravimetric analysis (TGA), and differential thermal analysis (DTA) revealed that the PT gel initially crystallized at an ...

Lead zirconium titanate alternatives for nanoactuators
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2013This paper describes the use of commercially available ceramic capacitors as an alternative for lead-containing and relatively expensive lead zirconate titanate (PZT)- based nanoactuators. A PZT actuator is compared with actuators made from both X5R- and Y5V-type ceramic dielectric capacitors using white light interferometry and a spectrometer.

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 ...

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 ...

Ferroelectric Lead Zirconate Titanate and Barium Titanate Nanotubes
Integrated Ferroelectrics, 2003Wetting of the pore walls of porous templates is a simple and convenient method to prepare nanotubes. Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors.
