Title

Effect of Shock Front Geometry on Shock Depolarization of Pb(Zr 0.52Ti 0.48)O₃ Ferroelectric Ceramics

Abstract

By use of experimentation, we detected a shock wave geometry effect on the depolarization of poled Pb(Zr₀.₅₂Ti₀.₄₈)O₃ Z(PZT 52/48) ferroelectrics. It follows from the experimental results that shock front geometry is one of key parameters in the shock depolarization of PZT 5248 ferroelectrics. This shock depolarization effect forms a fundamental limit to miniaturization of explosive-driven shock-wave ferroelectric generators (FEGs). Based on obtained experimental results, we developed miniature generators that reliably produce pulsed voltages exceeding 140 kV. © 2012 American Institute of Physics.
