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.

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 ...

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.

Ceramics are inorganic, non-metallic, solids that consist of a metal, a non-metal, a metalloid such as silicon, or a combination of these. Ceramics utilize ionic or covalent bonding, or both. When thinking of a ceramic you may think of pottery. This is perfectly reasonable since the word “ceramic” is derived from the Greek word keramikos, which means ...
