Structural Properties of Abrasive-Machined Lead Zirconate Titanate Ceramics

Measurement of Flexoelectric Effect in Lead Zirconate Titanate Ceramics*

Lead zirconate titanate (PZT) ceramics is usually used as a piezoelectric material. However it has characteristics of not only piezoelectricity but also flexoelectricity. Piezoelectricity is a phenomenon that electric polarization is induced by strain, and flexoelectricity is the one that the polarization is induced by strain gradient. In this study, flexoelectricity in poled soft PZT ceramics ...

Nonlinear properties of lead zirconate–titanate piezoceramics

Nonlinear properties of lead zirconate-titanate ~PZT! piezoceramics are investigated using ultrasonic second harmonic generation technique. When a sinusoidal ultrasonic wave of frequency v0 is sent into a nonlinear material, the second harmonic wave with frequency 2v0 is generated. Through measuring the absolute amplitude of the fundamental (v0) and of the second harmonic (2v0) waves, the ultra...

A. Response of Lead Zirconate Titanate Ceramics to Temperature Fluctuations

It has been found that some shapes of lead zirconate titanate (PZT) ceramics respond to rapid temperature fluctuations when mounted in a particular geometrical configuration. This effect is presumably caused by thermal stresses in the crystal which produce a voltage difference across the silvered surfaces. These units were originally constructed to serve as pressure transducers in a lowpressure...

Structural, Dielectric And Transport Properties Of Gd- Modified Lead Zirconate Titanate [Pb1-xGdx(Zr0.65Ti0.35)1-x/4O3] Ceramics

Polycrystalline samples of Gd-modified Lead Zirconate Titanate [PGZT; Pb1-xGdx(Zr0.65Ti0.35)1-x/4O3] ceramics (where, x = 0.00, 0.06 and 0.09) were prepared using high temperature mixed oxide method at sintering temperature 1450 K. Preliminary structural analysis through X-ray diffraction technique suggests their formation in single phase tetragonal crystal system at room temperature. From the ...
