It is experimentally found that the Eb(d) = γ · d -ξ law describing the thickness-dependent breakdown electric field for solid dielectrics at ambient conditions can be extended for dielectrics in other thermodynamic states. It follows from the experimental results reported herein that the breakdown field, Eb(d), of Pb(Zr₀.₉₅Ti₀.₀₅)O₃ (PZT 95/5) and Pb(Zr₀.₅₂Ti₀.₄₈)O₃ (PZT 52/48) ferroelectrics subjected to explosive adiabatic compression obeys the above-mentioned law in a wide range of voltages, up to 150 kV.
