Abstract The reaction sequence of PZT formation from the mixture of PbO-ZrO2-TiO2 has been extensively studied1-3. However, there have been no studies on the morphological changes occurring during the calcination process. The dependence of the characteristics and properties of the ceramic on the calcining conditions though has been well noted4–5, no ...

Interfacial reactions in PZT/Pd/PZT sandwich structures
Journal of Microscopy, 1995SummaryThe interfacial reactions of palladium foil and lead zirconate‐titanate (PZT) were studied using samples with a sandwich structure in the temperature range 1373–1523 K and under conditions where no lead is lost to the environment. The interfacial reactions were analysed using scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, X ...

Power harvesting with PZT ceramics
Analog Integrated Circuits and Signal Processing, 2007Piezoelectric materials have been proposed as embedded power source, which are capable of converting mechanical energy into electrical energy. However, power generated from a piezoelectric material usually comes with poor characteristics such as high voltage, low current and high impedance.

Properties of PZT/PZT ceramic piezocomposites
Bulletin of the Russian Academy of Sciences: Physics, 2010A method for obtaining PZT/PZT ceramic piezocomposites is developed. Samples of piezocomposites with a volume fraction of components from 0 to 100% are prepared and investigated. Various types of PZT type piezoceramics powders and milled PZT piezoceramics particles, as well as presintered piezoceramic granules, are used as matrix and filling components,

Dielectric, piezoelectric and elastic properties of PZT/PZT ceramic piezocomposites
2008 17th IEEE International Symposium on the Applications of Ferroelectrics, 2008A new method of PZT/PZT ceramic piezocomposites fabrication is proposed. Samples of piezocomposites with the volume fraction of components 0?100% for different PZT compositions were fabricated and measured. A line of chemically, thermally, and technologically compatible PZT matrix and filling compositions were chosen.

High-Performance PZT and PNN-PZT Actuators
2003Piezoelectric materials have been widely used as sensor and actuators in smart materials and structural systems [1,2]. Piezoelectric materials have attracted special attention among the many functional materials because they possess both the sensor and actuator functions, which can even be realized in a single element.

Microstructure of PZT Capacitor Structures
Ferroelectrics, 2003TEM, EDX, HREM studies of structure and phase content of lead titanate zirconate (PZT) thin ferroelectric films with the Ti/Zr atomic ration 47/53 prepared by sol-gel deposition with 0-30% exess of Pb have been carried out. The Si/SiO 2 /Ti/Pt substrates have been used as a metallization system.

Influence of the Incorporation of PZT (95/5) on PZT-5A Ceramics
Ferroelectrics, 2002A comparative study of the microstructure, electric and piezoelectric properties has been done on an unmodified PZT-5A and modified PZT-5A with PZT 95/5 prepared by two routes: mixed oxides and hydroxide coprecipitation. Piezoelectric and dielectric properties of the materials has been characterised.

Preparation of PZT fine powders for fabricating PZT thick films
Ferroelectrics, 2001Abstract A new process for preparation of PZT fine powder was proposed. By adding acetone and ammonia water to the precursor solution at suitable stages, nanosized powders with minimum agglomeration can be obtained. The effect of these additives on the powder preparation is analyzed according to the principle of the growth dynamics and the ...
