摘 要:The[Bi(NaK)]LaTiZrO(BNKLZT)energy storage ceramics were prepared by conventional solid-state reaction ***,surface morphology,dielectric,ferroelectric and energy storage properties of the BNKLBZTceramics were *** BNKLZTceramics showed perovskite,homogeneous and dense *** size was coarsened by Zr doping,and refined by La *** remnant polarization(Pr)and coercive field(Ec),slim P-E loops were obtained by introducing La and Zr *** optimum energy storage property was obtained for thecomposition of La=0.03 and Zr=0.03,with energy storage density of 0.84 J/cm at 80 kV/cm.
