| The (1-x)(Na0.5Bi0.5)TiO3–xBaTiO3 system (BNBT100x) is intensively studied as a candidate for lead-free ferroelectrics. BNBT6 ceramics, obtained by the self-combustion sol-gel method, hot pressing and recrystallization, were studied by synchrotron radiation and electron microscope techniques. Rietveld analysis of the XRD patterns provided the parameters of the coexisting crystalline structures as (globally) Pm3m and rhombohedral R3c phases for unpoled and poled samples. Both symmetries have been observed at the HRTEM as well. Permanent polarization of the cell structures for powder and ceramic samples has been confirmed by X-ray absorption near edge structure. | |
