Results on the piezoelectric performance of the ZTS-19 ferroelectric ceramic/clay composite are reported. In this composite, clay is regarded as an elastically soft piezo-passive component that strongly influences effective electromechanical properties and related parameters of the composite even at small volume fractions of clay mcl. Changes in the microgeometry of the composite are discussed, and its piezoelectric performance is interpreted in terms of models of the two- and three-component composites based on poled ferroelectric ceramics. Results of modeling are compared to experimental data. The studied composite is of interest as a piezoelectric material with relatively high piezoelectric sensitivity (g*33 > 50 mV · m/N), large anisotropy of the piezoelectric coefficients d*3j (5.4 < d*33/|d*31| < 8.2 at 0.01 ≤ mcl ≤ 0.05), and with considerable variation of the sound velocity vs.

Abstract
Results on the piezoelectric performance of the ZTS-19 ferroelectric ceramic/clay composite are reported. In this composite, clay is regarded as an elastically soft piezo-passive component that strongly influences effective electromechanical properties and related parameters of the composite even at small volume fractions of clay mcl. Changes in the microgeometry of the composite are discussed, and its piezoelectric performance is interpreted in terms of models of the two- and three-component composites based on poled ferroelectric ceramics. Results of modeling are compared to experimental data. The studied composite is of interest as a piezoelectric material with relatively high piezoelectric sensitivity (g*33 > 50 mV · m/N), large anisotropy of the piezoelectric coefficients d*3j (5.4 < d*33/|d*31| < 8.2 at 0.01 ≤ mcl ≤ 0.05), and with considerable variation of the sound velocity vs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
