    Abstract
  • In order to find out about the static electric field energy-storaging characteristics of lead zirconate stannate titanate ceramics doped with lanthanum, PbLa(Zr, Sn, Ti)O3 (PLZST) ceramics with different Sn/Zr ratios were fabricated using the conventional solid-state reaction of oxide method.The compositions of samples are all close to phase bound of ferroelectric (FE) and antiferroelectric (AFE).The energy-storaging characteristics of PLZST ceramics were investigated experimentally through hydrostatic pressure induced discharging.The results show polarized PLZST ceramics in the DC field are in a meta-stable FE state.Phase transitions from FE to AFE occur under the influence of the pressure, and the static electric field energy stored via polarization is released instantly, which leads to high-power current pulses.PLZST ceramics are totally depolarized after the discharging.The largest discharge current density and the largest electric field density are 5.0nA/cm2 and 9.45J/cm3 respectively.PLZST ceramics are ideal materials for explosive energy converter's power supply.
