Influence of high hydrostatic pressure on the crystal structure of barium titanate (Ba Ti O 3)
The crystal structure of BaTiO 3 has been investigated up to 4.4 GPa. The lattice becomes cubic at 3.4 GPa and stays cubic at higher pressures. The atoms do not occupy the ideal cubic positions up to highest applied pressure. The shortest Ti-O distance (parallel to the tetragonal c-axis) does not ch...

has been investigated up to 4.4 GPa. The lattice becomes cubic at 3.4 GPa and stays cubic at higher pressures. The atoms do not occupy the ideal cubic positions up to highest applied pressure. The shortest Ti-O distance (parallel to the tetragonal c-axis) does not change with pressure, if the errors are taken into account. All other Ti-O distances decrease with increasing pressure. |
