Abstract
We report the synthesis, structural characterization, morphologic and ferroelectric behavior of the Ba2TiZrO6 complex perovskite. The samples of Ba2TiZrO6 were synthesized through the standard solid-state reaction method. Rietveld analysis of X-ray diffraction patterns reveals that this material crystallizes in a rhombohedral structure, space group R-3 (#148), with cell parameter a=5.8038(7) A. Images of Scanning Electron Microscopy show the micrometric granular character of samples with 1.0 μm grain size. Results of semi-quantitative Energy Dispersive X-ray analysis are 97.5 % in agreement with the nominal stoichiometry of Ba2TiZrO6. Curves of polarization as a function of the applied electric field reveal that the Ba2TiZrO6 double perovskite behaves as a ferroelectric material at room temperature.
