Electromechanical properties of silicone-PZT (lead-zirconate-titanate) composite
SPIE Proceedings, 2010Dielectric elastomer composites are widely used electromechanical actuators. Compounding of dielectric elastomers with electroceramics helps to decrease the required electric field. In this work, silicone rubber was compounded with Lead- Zirconate-Titanate (PZT) electroceramic powder by the help of a silane coupling agent for better compatibility ...

Lead Zirconate Titanate (PZT) for M/NEMS
2017This section concentrates on the leading ferroelectric material used in thin-film piezoelectric MEMS: lead zirconate titanate (PbZr x Ti1−xO3) or PZT. PZT-based MEMS technology has been explored extensively for a variety of actuator applications [1] but has received less attention for RF MEMS resonator and filter applications.

Micromoulding of lead zirconate titanate (PZT) structures for MEMS
Journal of Electroceramics, 2007Thick (>10 μm) ceramic structures for applications in micro-electromechanically systems are typically fabricated using screen printing techniques or by printing a continuous film and subsequently etching the structure. This work presents a thick film lift off technique to create high aspect ratio thick Lead Zirconate Titanate (PZT) features on silicon ...

Tuning the morphology of lead zirconate titanate (PZT) nanostructures
Materials Letters, 2014Abstract We describe the synthesis of PZT nanoparticles using a hydrothermal method. We demonstrate that the morphology of the PZT nanoparticles can be controlled by tuning the concentration of the mineraliser, KOH. The experimental results show that for low concentrations of KOH (2 M) the reaction kinetics favor a high yield of spherical particles ...

Breakdown in lead zirconate titanate (PZT) thin film capacitors
Proceedings of 1994 IEEE International Symposium on Applications of Ferroelectrics, 2002Lifetime of PZT capacitors was defined and evaluated by measuring critical number of cycles where electrical degradation (increase of leakage current) begins to dominate polarization during fatigue tests. It was observed that external failure (electrode burst) occurs during fatigue before electrical degradation at high voltage and/or temperature.

Combined electromechanical dynamic fracture behavior of lead zirconate titanate (PZT)
Journal of the American Ceramic Society, 2022Abstract Coupon specimens of poled and depoled lead zirconate titanate (PZT) are examined under combined stress wave and electric loading conditions. Mode‐I crack initiation and fracture behavior is examined using ultrahigh‐speed imaging and two‐dimensional digital image correlation.

Characterization of hydrothermally synthesized lead zirconate titanate (PZT) ceramics
Materials Chemistry and Physics, 2004Abstract Lead zirconate titanate (PZT) powders were synthesized by hydrothermal method at various soaking temperatures (135–220 °C) and mineralizer concentrations (0.5–2.1 M KOH). Structural and morphological studies were carried out on hydrothermally synthesized PZT powders.

Alternating‐Current‐Assisted Poling of Lead Zirconate Titanate (PZT)
Journal of the American Ceramic Society, 1987A modification of the conventional poling procedure for piezoelectric materials was investigated because of inconsistencies in the literature. Preliminary investigations appeared to support the theory of ac‐assisted poling.

Solder transfer of lead zirconate titanate (PZT) thin films
2010 11th International Conference on Electronic Packaging Technology & High Density Packaging, 2010Functional ceramic thin films such as lead zirconate titanate (PZT) are of interest for a wide range of miniaturized devices. However the high processing temperatures of the films make integration of them into such devices challenging. Transfer of these films can allow integration onto substrates that are incompatible with the film deposition processes,

Hydrothermal and electrophoretic deposition of lead zirconate titanate (PZT) films
Journal of the European Ceramic Society, 2001Abstract Hydrothermal synthesis in conjunction with colloidal processing has been used to make PZT films in an aqueous solution. Fine PZT powders with a particle size of 200 nm and a narrow particle size distribution were synthesised hydrothermally at 300°C.
