Abstract

Ferroelectric

{Bi}_{4} {Ti}_{3} O_{12}

ceramics have been prepared by the method of reactive sintering. The ceramics exhibit good ferroelectric properties with a remanent polarization

P_{r} {=5.5×10}^{−2} {C/m}^{2}

and a coercive field

E_{c} =3

MV/m. High resolution x-ray photoelectron spectra of the atomic constituents of

{Bi}_{4} {Ti}_{3} O_{12}

were recorded. The obtained results indicate that oxygen vacancies are preferentially sited in the vicinity of Bi ions, in the

{Bi}_{2} O_{2}

layers.
