Raman and dielectric studies of 0.95Na0.5Bi0.5TiO3-0.05PbTiO3 ceramic

ABSTRACT0.95Na0.5Bi0.5TiO3-0.05PbTiO3 ceramic was prepared by a conventional solid phase sintering process. X-ray diffraction analysis shows that the obtained specimens possess perovskite structure with rhombohedral symmetry. The microstructure study showed a dense structure, in good agreement with the relative density of above 95% as determined by the Archimedes method. The crystal structure, phase transitions behavior and dielectric properties of these ceramics were investigated. Relaxor-like behavior was revealed.
