N2 - Lanthanum-doped 0.85Pb(Zn1/3Nb2/3)O3-0.10BaTiO3-0.05PbTiO3 ternary system ceramics were synthesized by the columbite method. The effect of lanthanum doping on dielectric, electrostrictive properties and electric hysteresis of the specimens was investigated. With the increase in lanthanum content, the content of perovskite phase and dielectric constant decreased, but the thermostability of the dielectric properties improved. When lanthanum content increased, electrostriction and electrostrictive coefficients decreased. The electric hysteresis of La-doped specimens also decreased, i.e. the remanent polarization and coercive fields decreased.
