چکیده انگلیسی
Anisometric-shaped particles were required for preparation of oriented ceramics by the reactive-templated grain growth method. Hexagonal plate-like particles of La4Ti3O12, (111)-type layered perovskite, were prepared by a molten salt synthesis (MSS), and the relationship between the morphology and crystal structure of the particles was analysed. La4Ti3O12 phase was obtained in KCl and NaCl fluxes whereas not obtained in LiCl. The developed plane of the plate-like particles was determined to be the (00l) plane and the side planes of the particle were found to be parallel the {h0l} planes. Surface steps with a height of approx. 0.9Â nm were measured on the developed plane. The step height corresponds to the distance between two adjacent interlayers, which indicates the lowest surface energy of the planes along the interlayers.
