Residual stress relief due to fatigue in tetragonal lead zirconate titanate ceramics

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...

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 ...

Residual stress effects on piezoelectric response of sol-gel derived lead zirconate titanate thin films

Piezoelectric properties of three sol-gel derived Pb Zr0.53Ti0.47 O3 thin film specimens of different thicknesses integrated onto Pt/Ti/SiO2 Si substrates are investigated to delineate the influence of residual stress on the strain-field response characteristics from other thickness related effects. Residual tensile stresses are determined from wafer curvature measurements for films ranging in ...

Effects of residual (or internal) stress on ferroelectric domain wall motion in tetragonal lead titanate

The effect of temperature on grinding-induced texture in tetragonal lead titanate (PT) has been investigated as a function of the magnitude of loading applied to the sample surface during grinding, using in situ x-ray diffraction (XRD) with an area detector. Compared to the ground PT under lower loading conditions (5 N), the ground PT under higher loading conditions (40 N) retains strong ferroe...
