The irreversible conversion of mechanical to electrical energy in ferroelectric ceramics of the Pb(Zr1-xTix)O3 type with a considerable proportion of zirconium is studied. The depolarization of the ceramics is studied for shock compressions between 0 and 30 kbar. The maximum electrical energy obtained at about 18 kbar, is of the order of 1.8 J/cm3 with a Pb(Zr0.965Ti0.035)O3 + 1% Nb2O5 and of the order of 0.8 J/cm3 with a Pb(Zr0.54Ti0.46)O3 + 1% Nb2O5.
