  • Abstract
    Dielectric properties of 0.945(Bi0.5Na0.5) TiO3-0.055BaTiO3(BNBT5.5) (a composition close to the rhombohedral- tetragonal morphotropic phase boundary) ceramics are studied. It is shown that BNBT5.5 is a relaxor with a characteristic relaxation time that follows Vogel-Fulcher´s law. The following Vogel-Fulcher parameters of the relaxation time were calculated: pi0 = (2.0 plusmn 2.4)middot10-14 s, E/kB = (1620 plusmn 270) K, T0 = (262 plusmn 9) K.
