The paper presents the results of a study of relaxation of the dielectric permittivities in constant electric fields upon switching the polarization of thin films of lead zirconate-titanate, crystallized at Coal Bucket different annealing temperatures.It is shown that the relaxation processes are characterized Other Filter Parts by at least three relaxation times which depend on the crystallization temperature.It is shown that the relaxation processes depend on the localization of lead oxide in the bulk of the film.
