Abstract: Breakdown voltages of two kinds of PZT95/5 ferroelectric ceramics with different grain sizes were investigated under shock compression. Weibull distribution model was used to analyze the experimental data. The results show that the breakdown voltage of PZT95/5 samples can be described by two parameter Weibull distribution. According to the density function and failure probability function of the Weibull distribution, PZT95/5 ceramics with fine grains possess more optimum breakdown voltage distribution than PZT95/5 ceramics with coarse grains.

Key words: PZT95/5 ferroelectric ceramics, shock compression, breakdown voltage, grain size
