Abstract

The （1-x）(K

[（1-x） KNN-x CZ

]

piezoelectric ceramics are prepared by conventional solid-phase sintering. The effects of the doping of CaZrO

and the quantitative change（ x = 0. 02

0. 06

0. 08） on the microstructure

surface morphology

piezoelectric properties

ferroelectric properties and dielectric properties of the ceramics are studied. The resul

ts show that the doping of CaZrO

does not change the crystal structure of the ceramic samples

and all the samples are single perovskite structure. The introduction of CaZrO

can make the grains more uniform

improve the compactness. And also it can increase the piezoelectric constant

the residual polarization strength and reduce the coercive field

which extent promotes the optimization of the electrical properties of KNN-CZ ceramic samples. The unidirectional electric strain（ ε）

Curie temperature dielectric constant peak（ ε

） and piezoelectric constant( d

) of [（ 1-x） KNN-xCZ

]

piezoelectric ceramics reach the maximum value when x = 0. 04

respectively

ε = 0. 055 %

= 5 262

= 188 p C/N.
