Lead zirconate-titanate piezoelectric ceramics

British Journal of Applied Physics, 1961
The disadvantages of ceramics based on barium titanate has limited many of the possible applications of this type of piezoelectric material. The Curie point is low and it is inefficient in electromechanical conversion. The discovery of the piezoelectric properties of the solid solution ceramics based on lead zirconate and lead titanate has stimulated ...

Analysis of lead titanate-zirconate ceramics

Analytica Chimica Acta, 1966
Abstract Differential cathode-ray polarography is applied to the direct determination of lead, titanium and niobium in lead titanate-zirconate solid-solution ceramics containing small additions of niobium pentoxide. Titanium and niobium are determined in buffered EDTA solution at pH 4.0 and lead in 1 M hydrochloric acid.

Switching of polycrystalline lead zirconate titanate

Journal of Physics D: Applied Physics, 1969
Measurements are described of the switching currents in polycrystalline lead zirconate titanate as a function of time and applied electric field. Samples of three compositions were investigated: Pb(Zr0·65 Ti0·35)0·99 Nb0·01 O3, Pb(Zr0·52 Ti0·48)0·99 Nb0·01 O3 and Pb Zr0·55 Ti0·45 O3. The results of these measurements show that the switching current has

Vaporization of Lead Zirconate‐Lead Titanate Materials

Journal of the American Ceramic Society, 1967
A thermogravimetric investigation of the vaporization of cold‐pressed Pb(Zr 0.65 Ti 0.35 )O 3 in vacuum from 690° to 1130°C shows that the vaporization occurs in two steps.

Monolithic crystalline lead zirconate titanate aerogels

Journal of Non-Crystalline Solids, 1998
Abstract Stoichiometric lead zirconate titanate (PbZr 0.53 Ti 0.47 O 3 , PZT) alkogels were prepared by a sol–gel technique. Drying under ambient conditions yielded xerogels while solvent exchange and supercritical drying either in carbon dioxide or isopropanol led to highly porous aerogels.

Optical Study of Lead Zirconate-Titanate

Journal of the Physical Society of Japan, 1965
Single crystals of the lead zirconate-titanate solid solution containing 85 percent and those containing less than 40 percent of lead zirconate have been prepared from a molten solvent of a mixture of KF and PbF 2 , and the measurements of optical birefringence have been made. They are all optically negative.

Lead zirconate titanate-lead silicate piezoelectric glass-ceramics

Proceedings of 1994 IEEE International Symposium on Applications of Ferroelectrics, 2002
Piezoelectric glass-ceramics consisting of lead zirconate titanate in a lead silicate matrix have been developed. A small region of compositions in this system yield the desired combination of glass formability, densification and crystallization behavior, and piezoelectric properties.

Fatigue In Bulk Lead Zirconate Titanate Actuator Materials

Advanced Engineering Materials, 2005
AbstractFatigue in ferroelectric ceramics is the gradual change of material properties with cyclic loading. It is caused by microscopic material modifications of mechanical or electrical origin. Due to the electromechanical coupling, both mechanisms can yield similar or even identical changes in properties.

Low‐Temperature Preparation of Nanocrystalline Lead Zirconate Titanate and Lead Lanthanum Zirconate Titanate Powders Using Triethanolamine

Journal of the American Ceramic Society, 1998
Nanocrystalline lead zirconate titanate (PZT) powders, with a Zr:Ti ratio of 60:40, have been prepared from a solution of triethanolamine (TEA) and Ti 4+ , Zr 4+ , and Pb 2+ ions.
