Pure and niobium doped bismuth titanate ceramics (Bi 4 Ti 3−x Nb x O 12 (BTN)), with x ranging from 0 to 0.4 were prepared by the polymeric precursor method. X-ray diffraction showed no secondary phases. Increasing niobium content leads to more resistive ceramics. The shape and size of the grains are strongly influenced by the niobium added to the system. The dielectric...
In this study, the effect of bismuth content on the crystal structure, morphology and electric properties of barium–bismuth–tantalate (BBT) ceramics was explored with the aid of X-ray diffraction (XRD), scanning electron microcopy (SEM), dielectric properties and ferroelectric hysteresis loops. BaBi 2 Ta 2 O 9 (BBT) ceramics have been successfully prepared by the solid-state...
