Large-strain piezoelectric ceramic material and preparation method thereof
The invention discloses a large-strain piezoelectric ceramic material and a preparation method thereof, and belongs to the technical field of electronic component manufacturing. The general chemical formula of the piezoelectric ceramic material is Pb1-xSrx[(Ni1/3Nb2/3)0.3(ZryTi1-y)0.695]O3+z wt% Sb2O3, wherein x is greater than or equal to 0 and less than or equal to 0.015, y is greater than or equal to 0.42 and less than or equal to 0.44, and z is greater than or equal to 0 and less than or equal to 1.5. The piezoelectric ceramic material is obtained by adopting an electronic ceramic preparation process and carrying out multi-component compounding and doping modification on the basis of a PZT binary system, and has a relatively high dielectric constant ([epsilon]33T/[epsilon]0=3800 +/-12.5%), a piezoelectric strain coefficient (d33=660 +/-15% pC/N) and an electro-mechanical coupling coefficient (kp=0.66 +/-6.0%). The piezoelectric ceramic material is mainly applied to a micro-displacement driver, can generate high strain under certain electric field intensity, effectively improves the reliability of a device, optimizes rear-end equipment, improves the frequency stabilization effect of a laser, and can be widely applied to the fields of electronic information technology, aerospace, national defense industry and the like.
