A simple method, chemical precipitation at low temperature from Ca(NO3)2·4H2O and (NH4)2HPO4 to tailor single phase, highly crystalline nanocrystal hydroxyapatite (HAp) powders was introduced in this paper. HAp powders with controlled morphologies (spherical and rod-like) and different grain sizes have been obtained by varying the reaction temperature, reaction mode, and heat treatment accordingly. X-ray diffraction (XRD) results combined with the Fourier transform-infrared spectroscopy (FT-IR) indicates that the single phase, nanocrystal HAp powder could be obtained in one-step without further heat treatment. At 40 °C with a quick mixing mode, ultra-fine complete spherical HAp particles with diameter range size of 20–50 nm could be obtained.
