Synthesis and characterization of fluorine-containing hydroxyapatite by a pH-cyclic method

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

The synthesis of different fluorine-containing hydroxyapatite (FHA) powders, by changing the sodium fluoride (NaF) to HA molar ratio, was described. The FHA powders with various fluorine contents were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). It was found that the efficiency of fluorine incorporating into hydroxyapatite decreased with increasing the NaF/HA ratio. It was observed that heterogeneous FHA particles, with a mixture of fluorine-deficient fluoridated hydroxyapatite (DFHA) and fluorine-rich fluoridated hydroxyapatite (FFHA) particles, were precipitated initially. It was suggested that the mixture of DFHA and FFHA transformed into homogeneous FHA after calcination at 1200°C for 1 hour.
