ABSTRACT
The (Na0.5Bi0.5)1-xBaxTiO3 ceramics (x = 0.12, 0.125, 0,13) were fabricated by conventional solid phase sintering process. The samples were characterized by the bulk density which exceeds 95% of the theoretical density. The X-ray diffraction analysis shows an increase of lattice parameters with the rise in Ba2+ content. The electric permittivity broad anomaly is shifted to a lower temperature range after Ba doping of NBT. The hysteresis loops measurements also show changes in comparison to pure NBT. Relaxor behavior of investigated materials was revealed.
