摘要: Fluorapatite-zinc oxide (FAp-ZnO) composite nanopowders were successfully prepared via mechanochemical process. Characterization of the products was carried out by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) analysis, energy dispersive (EDX), and field-emission scanning electron microscopy (FE-SEM) techniques. Results revealed that in absence ZnO which produced hydrothermal method, single-phase FAp had high-crystalline structure with appropriate morphological features. Furthermore, after 5 h milling presence 5 wt.% ZnO, FAp-5 wt.% no impurity phase obtained. Structural studies illustrated up to not accompanied a remarkable change structural Moreover, gained powders presented an average crystallite size about 40 nm for FAp. The FE-SEM observations indicated experimental outcome cluster-like consisted several small particles. Finally, results propose new approach prepare commercial amounts novel FAp-based high quality suitable
