Abstract

We investigated the dynamic compressibility of a piezoceramic composed of lead zirconatetitanate (LCT) and its depolarization by shock waves over the pressure range 100–500 kbar. We also observed the changes that persisted in the specimens after brief compression at pressures of 350 and 500 kbar. The dependence of the piezocurrent on time was used to calculate the dielectric permeability and conductivity of the ceramic beyond the shock-wave front over the pressure range investigated. This article discusses the possibility of a phase transition to the paraelectric phase in LCT during compression by a shock wave.
