The results of long-time relaxation in the piezoelectric Pb(Zr,Ti)O3 ceramics after the cessation of excitation (by electric field, heating, mechanical compression) are presented. Reduce of the dielectric constant according the logarithmic law takes place during ageing. Such behaviour is associated with relaxation of the electric charge, which is precipitated at partial depolarization of ceramics and localized on nanoscale defects of lattice.
