高压电活性PNN-PZN-PBSZT陶瓷的结构及性能
Structure and Properties of PNN-PZN-PBSZT Ceramics with High Piezoelectric Activity
摘要
Abstract
xPb(Ni1/3Nb2/3)O3-0.01Pb(Zn1/3Nb2/3)O3-(0.99-x)Pb0.82Ba0.08Sr0.10Zr0.56Ti0.44O3(xPNN-PZN-PBSZT) piezoelectric ceramics were preparedvia conventional ceramic processing with columbites as precursors. The influence of NiNb2O6 content on the phase structure,piezoelectric and dielectric properties was investigated. ThexPNN-PZN-PBSZT ceramics that components are near the morphotropic-phase-boundary (MPB) exhibit a perovskite structure. The phase translates from tetragonal to rhombohedral structure as thex increases. The piezoelectric, mechanical and dielectric properties ofxPNN-PZN-PBSZT ceramics are improved due to the introduction of PNN. The ceramics withx 0.015 show better piezoelectric properties. The piezoelectric constant,d33, relative permittivity,εr,theCurie temperature,Tc, and electromechanical coefficient,kp, of the ceramics are 998pC/N and 5498, 140℃ and 74.61%, respectively. However, the maximumkp is 76.26% asx=0.02.关键词
