Investigation of dielectric properties of La0.33NbO3 ceramics

La0.33NbO3 ceramics was prepared via conventional solid-state reaction method. Structural analysis show the existence of single phase of La0.33NbO3 has been synthesized with an average particle size of 2 µm – 4 µm estimated from FESEM image. Detailed investigation on the dielectric properties and AC conductivity of the La0.33NbO3 ceramics in a wide range of frequency (800 Hz – 5 MHz) and temperatures (30 °C – 300 °C) revealed that these properties are strongly temperature and frequency dependent.
