- Abstract
- The analysis of relaxation processes occurring in different both frequencies and temperature intervals. Used to describe a number of models of relaxation, the ability to correctly describe the blurring of the phase transition in real objects. Found that the complication of the phase composition of objects determines non-Debay nature of the dielectric spectra. In the high temperature region has revealed an anomalous permittivity, explained their reasons. The correlations of activation energy of relaxation process corresponding to the transition from the ferroelectric-relaxor - classic ferroelectric and phase composition of ceramics. The conclusion about the feasibility of the studied ceramics with giant dielectric constant in the low-frequency technique.
