Özet

Pure and 2.5 mol.-% Y3+ and F- doped nanohydroxyapatites were synthesised by a precipitation method and sintered at 900 and 1100 degrees C to investigate their densification and structure. X-ray diffraction and Fourier transform infrared spectroscopy methods were performed to identify the presence of phases and bonds after the sintering respectively. Densification of hydroxyapatite was improved by the addition of these ions. No second phases were observed by X-ray diffraction method. Structure of the materials was hexagonal. Fourier transform infrared spectroscopy investigations showed that the Y3+ and F- doped hydroxyapatites had F- bonds in addition to OH- bonds after the sintering.
