Abstract

Dense (1-x)BaTiO3-xBiYbO(3) (BBTYb) ceramics were fabricated by the solid state reaction method. According to X-ray diffraction data, the average crystal symmetry of x = 0.06 ceramics is better described by the centrosymmetric cubic Pm (3) over barm space group. Raman spectroscopy supports a change in the average crystal symmetry at x >= 0.06, but also reveals differences in the local crystal structure for x = 0.06 ceramics, for which the local crystal symmetry departs from cubic, as indicated by the presence of Raman spectra.
