Dip-coating conditions and modifications of lead titanate and lead zirconate titanate films

Journal of Materials Science, 1990
The 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 ...

Switching Frequency Dependence in Thin Films of Lead Titanate and Lead Zirconate Titanate

Ferroelectrics, 2008
The dependencies of coercive field and internal bias field on the frequency of the applied external field were experimentally studied in the films of lead titanate and lead zirconate titanate in a wide temperature range. It was demonstrated that with the frequency increase in the above films a build up of coercive field and internal bias field is ...

Layered lead zirconate titanate and lanthanum-doped lead zirconate titanate ceramic thin films

Journal of Materials Research, 2002
The physical layering of sol-gel-derived lead zirconate titanate (PZT) 52/48 and lanthanum-doped PZT (PLZT) 2/52/48 on platinized silicon substrates was investigated to determine if the ferroelectric properties and fatigue resistance could be influenced by different layering sequences.

Lead Zirconate Titanate

2018
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 ...

Ferroelectric Lead Zirconate Titanate and Barium Titanate Nanoshell Tubes

MRS Proceedings, 2003
ABSTRACTWetting of the pore walls of porous templates is a simple and convenient method to prepare nanoshell tubes. Wafer-scale fabrication of ferroelectric lead zirconate titanate and barium titanate nanoshell tubes was accomplished by wetting porous silicon templates with polymeric precursors.

Complex rare-earth substituted lead titanate piezoceramics

14th IEEE International Symposium on Applications of Ferroelectrics, 2004. ISAF-04. 2004, 2005
Rare earth substituted piezoelectric ceramics with the composition Pb x RE y Ti 0.98 Mn 0.02 O 3 , with RE = Pr, Pr+Eu, Gd+Nd, and a few percent of bismuth to partially substitute the lead, have been prepared by solid state reaction of oxide powders. Structural and morphological investigations were performed on the poled samples.

Hydrogen diffusion in lead zirconate titanate and barium titanate

Journal of Applied Physics, 2012
Hydrogen 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 ...

Fractoemission from Lead Zirconate‐Titanate

Journal of the American Ceramic Society, 1985
We present measurements of the electron, positive ion, and photon emission accompanying the fracture in vacuum of poly‐crystalline 95/5 lead zirconate‐titanate. The intensities of the charged‐particle components of this fractoemission are shown to depend strongly on the direction (relative to the direction of fracture) and magnitude of polarization ...

Multilayer Lead Zirconate Titanate and Barium Titanate Ferroelectric Capacitors

MRS Proceedings, 1996
AbstractFerroelectric PbZrxT1−xO3 (PZT) thin films have been deposited on Pt coated Si substrates by if magnetron sputtering. The optimized processing condition to obtain proper stoichiometric PZT, the desired ferroelectric perovskite phase, and better dielectric properties was demonstrated using a PZT target with Pb(Zr+Ti) ratio of 1.2 and depositing ...
