Dispersion of Dielectric Permittivity in Ferroelectric Ceramics (K0.5Na0.5)NbO3 Modified with BaTiO3
Dispersion of the dielectric constant of ferroelectric ceramics based on (K,Na)NbO3 modified by barium titanate with a concentration of 0.01, 0.02 and 0.04 mol % is studied in the temperature range of 25–120°C. Patterns in the effect the modifying additive has on the dispersion of the dielectric constant in the frequency range of 0.25–105 Hz are determined.
