Abstract
The physicochemical properties of synthetic fluoridated hydroxyapatites were studied.The crystallinity increased initially, then decreased, and finally increased again with increasing fluoride content.In contrast to the unexpected crystallinity phenomena, the solubility in acetate buffer solution at pH4.0 and 37℃ decreased monotonically with increasing fluoride content, and scarcely changed above 2mmol/g of fluoride content, in which CaF2 was detected with fluorapatite.
