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.

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 ...

Dip-coating conditions and modifications of lead titanate and lead zirconate titanate films
Journal of Materials Science, 1990The modifications of dip-coated lead titanate (PT) and lead zirconate titanate (PZT) films strongly depend on the film thickness and the substrate in addition to the heat-treatment temperature. At 500 to 600 ° C, metastable paraelectric pyrochlore grew on glass plates (amorphous plates) when the thickness of the coated films produced by one coating ...

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.

Hydrogen diffusion in lead zirconate titanate and barium titanate
Journal of Applied Physics, 2012Hydrogen is a potential clean-burning, next-generation fuel for vehicle and stationary power. Unfortunately, hydrogen is also well known to have serious materials compatibility issues in metals, polymers, and ceramics. Piezoelectric actuator materials proposed for low-cost, high efficiency high-pressure hydrogen internal combustion engines (HICE) are ...

The processes of polarization fatigue in PbTiO3 and Pb(Zr0.5Ti0.5)O3 films on silicon substrates have been studied by the method of switching in rectangular pulsed fields. Dependences of the switchable polarization, the maximum switching current imax, and the switching time τs on the number of switching cycles have been obtained from the data on the ...

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 ...
