PbLa（Zr，Sn，Ti）O3反铁电陶瓷的静电场能存储特性
Static Electric Field Energy-Storaging Characteristics of PbLa(Zr,Sn,Ti)O3 Ceramics
摘要
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 5.0 nA/cm2 and 9.45 J/cm3 respectively. PLZST ceramics are ideal materials for explosive energy converter’s power supply.关键词
