 Abstract: Hexagonal prismatic crystal-like entities of fluorapatite-gelatine nanocomposites were grown by double-diffusion in gelatine gels. The Bragg pattern of the specimens (containing 2.3(3) wt.-% gelatine) is consistent with fluorapatite. TEM images together with atomistic computer simulations reveal the material to be best described as a mosaic-dominated nanocomposite superstructure. Intrinsic electric dipole fields (detected by electron holography), generated by a non-classical crystallization process of composite nanoboards (elongated platelets), cause the integration of a meso/macroscopic pattern (symmetry: 6/m) of gelatine microfibrils into the superstructure matrix.
