RELAXOR BEHAVIOR OF BaBi4Ti4O15
Apstrakt
Dense BaBi4Ti4O15 ceramics were prepared by conventional solid state reaction
from appropriate oxide mixture. Dielectric properties were investigated in a wide range
of temperatures and frequencies. A modified Curie-Weiss relationship is used to study
the diffuseness behavior of a ferroelectric phase transition. The dielectric relaxation rate
follows the Vogel-Fulcher relation with Ea = 0.013 eV, ν0 = 2.09 ×108 Hz and Tf = 651 K.
Impedance investigations show only a single semicircle which can be ascribed to the
grain component for all investigated temperatures. The calculated values of activation
energy Ea is 1.02 eV.
