Dielectric behaviors and relaxor characteristics in Bi0.5Na0.5TiO3-BaTiO3 ceramics
Microstructure and dielectric behaviors of heating/cooling and bias-field were investigated in lead-free ceramics (1−x)Bi0.5Na0.5TiO3−xBaTiO3 (BNT−xBT, x=0, 0.02, 0.04, 0.06, 0.08 and 0.10). The relaxor characters and the Vogel–Fulcher law of frequency-dependent dielectric properties were analyzed....
