Abstract The crystal growth of hydroxyapatite (HAp) in the presence of hexadecylamine was investigated by the patterns of X-ray diffractions (XRD), Fourier transformed infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and selected-area diffraction (SAD) in this work. Results show that: due to its high polarity and high charged density, the organic film could increased the ions supersaturation on its surface, thus leading to a fast growth of pure HAp crystals. Moreover, the positive headgroups in the organic film could act as recognized nucleation sites and orient the growth of HAp crystals along <0001> direction.
