As an inorganic component of shark teeth and some exoskeletons of molluscs, fluoroapatite, Ca10(PO4)6F2, is a highly relevant biomineral. Human teeth consist mainly of carbonated hydroxyapatite, Ca5-x(PO4CO3)3OH, and do not contain high levels of fluoride (overall less than 0.1 wt %); on the surface of human teeth, between 0.05 and 0.1 wt % fluoride was found. However, the interaction between fluoride and calcium phosphate is important to understand the formation and dental protection of teeth. In this paper we report the synthesis of fluroapatite of various size and chemical composition under simple and relatively mild reaction conditions. Precipitation method and ultrasonic method were used for the fabrication of fluorapatite. And various solutions were used to different shape of fluorapatite. Using scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (XRD), the mechanism of how these structures formed was explored.
