| dc.description.abstractEn | Based on the Debye theory, we have determined the evolution of the dielectric permittivity of the ceramic with composition KTa<sub>0.6</sub>Nb<sub>0.4</sub>O<sub>3</sub> as a function of temperature and frequency. This evolution shows that this composition exhibits a ferroelectric–paraelectric phase transition at 360 K with dispersion at high frequencies (10<sup>6</sup>–6 × 10<sup>8</sup> Hz). A comparison between experimental and numeric calculation of dielectric permittivity for this solid solution has been suggested using a Gaussian distribution of the relaxation times, which was introduced in Debye relations. The numerical results were in agreement with experimental data. | |
