AbstractDensed BiFeO3(BFO) ceramics were sintered by using soft chemical derived fine powders. The microstructures, polarization and dielectric properties were investigated by means of X-rays diffraction (XRD), Scanning electron microscope (SEM), ferroelectric test system and impedance analyzer. The XRD patterns indicate that BFO ceramics with a single distorted perovskite structure are formed and no secondary phase appears in the ceramics. Through the dielectric response investigated over a wide range of temperature and frequency, it is found that the BFO ceramic sintered at 800 degrees C exhibited high dielectric permittivity and two dielectric relaxations. The remanent polarization and maximum polarizations were 0.232 and 0.443C/cm(2), respectively (at 25kV/cm).
