Abstract

A novel method for synthesizing anisotropically shaped particles of materials having cubic symmetry is reported. Anisotropically shaped single-crystal particles of cubic SrTiO3 were obtained by epitaxial growth on tabular tetragonal Sr3Ti2O7. Transmission electron microscopy revealed that both the shape and the size of the single-crystal particles was regulated by selecting a precursor material that can act as a reaction site in molten KCl and has an epitaxial relation with SrTiO3. The [001] and [110] directions of tabular SrTiO3 are parallel to the [001] and [110] directions of the Sr3Ti2O7 host particle, respectively. Tabular SrTiO3 particles with rectangular faces having an edge length of 10–20 μm and a thickness of ˜2 μm were obtained by reacting TiO2 and tabular Sr3Ti2O7 particles of the same edge length in molten KCl.
