摘要:
In this paper, we report a raman spectroscopy and X-ray diffraction investigations on lead-free (1-x)(Na0.3Bi0.5)TiO3-xBaTiO(3) (NBT-BT) solid solution ceramics over a composition range of 0 <= x <= 0.10 at room temperature. The Raman curves were fitted to the individual Raman peaks. The obtained peaks were analyzed by observing the changes in their respective peak positions and intensities with increasing of BaTiO3. In light of the obtained observations, it is suggested that a MPB of rhombohedral and tetragonal phases of the studied system lies at the composition of x = 0.065. Further support for the obtained MPB was drawn from X-ray diffraction measurements.
