摘要
La-doped 0. 85Pb (Zn1/3Nb2/3) O3-0. 10BaTiO3-0. 05PbTiO3 ternary ceramics were synthesized by the columbite method. The effect of La-doping on phase structure, dieletric constant, electrostrictive properties and electric hysteresis of PZN-based ceramics were investigated. With lanthnum content increasing, the content of perovskite phase and dielectric constant decreased, and meanwhile dielectric temperature stability improved. With the increment of lanthanum content, the electrostriction and electrostrictive coefficients decreased, and at the same time the strain and electric hysteresis decreased, i. e., remanent strain, remanent polarization and coercive fields decreased.
