Interactions of fluoride ions with calcium phosphate crystals have attracted many attentions mainly because of their biomedical implications. While an appropriate amount of fluoride is useful in preventing tooth decay, high concentrations of fluoride ions in potable water can lead to the fluorosis in bone and teeth. Such high concentrations may originate from geological and industrial sources. In the present work, pure hydroxyapatite (HA), octacalcium phosphate (OCP), and dicalcium phosphate dihydrate (DCPD or brushite) were prepared, and the synthesized crystal phases have been confirmed by energy dispersive X-ray spectroscopy (EDS) and wide angle X-ray diffraction (WAXD). Also, the obtained calcium phosphate crystals have been exposed to sodium fluoride aqueous solutions to study interactions of fluoride ions with the calcium phosphate crystal family. |
