摘要：

Resistivity of the shocked PbZr0.95 Ti-0.05 O-3 (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 10(7) -10(11) Omega cm to a minimum of 40 Omega cm and then rises to values between 120 and 140 Omega cm until the end of the shock depoling.
