The growth of cracks under the influence of high voltage cyclic electric field in 8/65/35 lanthanum lead zirconate titanate samples was studied. The remanent polarization, coercive field and complex dielectric constant were measured as a function of the number of switching cycles. During the measurement the salt water solution was penetrating through the sample.
