The atomic-scale structure of nanocrystalline BaTiO3 powders has been studied using high-energy X-ray diffraction, X-ray absorption fine structure, and atomic pair-distribution function analysis techniques. Studies show that the materials are well-ordered at nanometer distances. The three-dimensional atomic ordering in BaTiO3 is cubic on average, but locally shows slight tetragonal distortions, similarly to that occurring in coarse-grained bulk crystals. Ferroelectric coherence is facilitated in part by control of the particle morphology. The spatial extent of cooperative ferroelectric distortions is found to be degraded in nanometer-sized building blocks. The new structural information obtained helps one to understand better the dielectric properties of these nanomaterials.
