Effect of CO2 Ion Doping on Characteristics of Nanostructure Hydroxyapatite

Noori A, Farhood Ziaie and Shafaei M

In this research work, carbonated hydroxyapatite samples with different carbonate contents were prepared using ion implantation method. Pure nano-structure hydroxyapatite samples were implanted by 80 keV CO2 + ions during different times of 4, 8, 16, and 24 min using an ion implantation devise. The resulting materials were tested by X-ray diffraction, Fourier transform Infrared spectroscopy, and transmission electron microscopy, electron spin resonance systems before and after the implantation. The results confirmed the doping of carbonate group into the hydroxyapatite structure, and show that the presence of carbonate in the structure of hydroxyapatite decreases the degree of crystallinity. Moreover, it was observed that the increasing of ion implantation time caused to decrease the average grain size of the hydroxyapatite sample.
