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

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 ...

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.

Evidence of a transformation from tetragonal to rhombohedral phases in a 80/20 mixture of lead ziconate titanate (PZT) (53/47) and lead magnesium niobate-lead titanate (PMN-PT) (65/35) was observed by x-ray diffraction, microstructural analysis, dielectric spectroscopy, and electrically-induced strain measurements.

3-3 composites with different ceramic phases-lead titanate zirconate and lead titanate
[Proceedings] 1990 IEEE 7th International Symposium on Applications of Ferroelectrics, 2002Composites consisting of ceramics and polymer show improved performance when working with low acoustic impedance materials, compared to conventional dense piezoceramics. This study concentrates on composites with a 3-3 structure, made of hard epoxy and a ceramic phase either of lead zirconate titanate (LZT), modified lead titanate (mLT) or pure lead ...
