چکیده مقاله:

The present investigation reports on a novel precursor used for fabricating the F-substituted hydroxyapatite. The synthesis of nanostructured fluorapatite (FA; Ca10(PO4)6(OH)2-xFx) was explored from the starting materials of CaCO3, P2O5 and CaF2 via a mechanochemical process. The products, which were prepared by different times of milling (10 min, 2, 4, 6, 8, 10, 12 and 14 h) and different contents of fluorine ion (0, 25, 50, 75 and 100 percent of substitution), were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM) techniques and Fourier transform infrared (FTIR) spectroscopy. Transmission electron microscopy (TEM) analysis demonstrated that FA nanoparticles with an average diameter of about 15-30 nm were prepared. This is in agreement with XRD patterns. By this new precursor, nano bio ceramics synthesized very comfortable. Byproduct of this reaction was just CO2. Then purity of products was increased by using CaCO3. Also smaller nano bio ceramics with narrower particle size distribution can be made by using this method and novel and cheap precursor. The high productivity of the procedure opens a window to produce commercial plenty of fluorapatite nanoparticles
