Abstract: Dielectric properties of nickel-doped PbZrO₃ ceramics were measured at frequencies from 200 Hz to 50 kHz. When the ceramics were heated up to 700^oC, evidence of a peak in the dielectric constant was observed in   the paraelectric phase. It was also found that the peak observed strongly depended on the applied frequency.   Measurements of the frequency shift of the dielectric constant peak give an activation energy of 1.37 eV.
