Abstract

Crystal structure of a ferroelectric barium titanate Ba Ti2 O5 was investigated by the Rietveld analysis of neutron powder diffraction data measured at 706 °C. The crystal structure of Ba Ti2 O5 at 706 °C was refined assuming the centrosymmetric monoclinic A2m space group. The crystal structures of the high-temperature A2m and low-temperature A2 phases are similar. The displacement of atoms along the b axis is accompanied by the paraelectric A2m to ferroelectric A2 phase transformation. The A2m-A2 transition is not reconstructive but displacive.
