摘要
采用固相反应法制备了Pb0.96La0.06(Zr1-xTix)O3陶瓷,研究了Ti含量对所制陶瓷的电性能和储能特性的影响。结果表明,PbLa(ZrTi)O3陶瓷介电常数与电场强度呈非线性变化关系。当Ti含量x为0.08时,所测电滞回线细长狭窄,并呈下凹趋势,此时极化强度为22.18×10–6 C/cm2,储能密度为1.06 J/cm3。通过流延法制备的脉冲功率电容器击穿电压可大幅度提升,储能密度达1.95 J/cm3,具有高能量转换效率。
The Pb0.96La0.06（Zr1-xTix）O3 ceramics were prepared by solid-phase method. The electrical properties and energy storage characteristics of the ceramic with different contents of Ti were investigated. The result show that this relation is nonlinear between the permittivity and electric field strength for PbLa（ZrTi）O3 ceramics. When the Ti content （x） is 0.08%, hysteresis loop is narrow and concave. Meanwhile polarization is 22.18×10^-6 C/cm2, energy storage density is 1.06 J/cm3. The breakdown voltage can be greatly improved for pulsed power capacitors by casting process. The energy storage density reaches 1.95 J/cm3 and it has high charge-discharge efficiency.
