Mechanism for Fluorine Inhibition of Diffusion in Hydroxyapatite

Abstract

NEW NMR results for a mineral hydroxyapatite have been obtained which, in combination with recent precision X-ray crystallographic studies, provide a detailed model of the locations of the impurity-fluoride ions in hydroxyapatite, their influence on neighbouring hydroxyl ions, and a mechanism by which small amounts of fluorine can strongly inhibit diffusion.
