In this work, we have performed Raman scattering measurements in
Ba2BiSbO6 ceramics in the temperature range from 10 to 573 K. The Raman
spectra were examined using group theory to analyze the decomposition of
the reducible representation of the vibrational modes and with a virtual
octahedral model. At room temperature, five modes were observed. At low
temperatures, the spectra subtly showed the rhombohedral-monoclinic
phase transition, which was identified by changes in the Raman intensity
of the bending and symmetrical stretching SbO6 octahedral modes. The
cubic-rhombohedral phase transition was not clearly evident in the
high-temperature Raman data. Copyright (C) 2009 John Wiley & Sons, Ltd.
