Resistivity of PZT 95/5 ferroelectric ceramic under shock wave compression

Resistivity of the shocked PbZr0.95Ti0.05O3(PZT 95/5) ferroelectric ceramic has been determined under shock wave compression. A physical model has been developed which takes into account the finite resistivity of ferroelectric ceramic compressed by shock wave propagating in a direction perpendicular to the remanent polarization vector. The results reveal that under the pressure of about 2.0 GPa under short circuit, the resistivity of the shocked PZT 95/5 ceramic drops very quickly from 107—1011Ωcm to a minimum of 40Ωcm and then rises to values between 120 and 140Ωcm until the end of the shock depoling.
