This paper focused on the resistivity variation of PZT 95/5-2Nb ferroelectric ceramics under shock compression. First, release current decreasing which is a sign of PZT 95/5-2Nb ceramic resistivity decreasing has been observed by a reasonable sample size design in shock-compact experiment. A depoling current model considering PZT 95/5-2Nb ceramic resistivity decreasing has been obtained. Experiment results analyzed with the model indicate that the resistivity of PZT 95/5-2Nb ceramics reduces to the order of 100 Ω m with applied shock stresses range from 2.5 to 3 GPa.
