A Preliminary Study on in vitro Behaviors of Sol-Gel Derived Nano Fluorapatite/Hydroxyapatite Coatings
|
Abstract:
A fluorapatite/hydroxyapatite coating on Ti6Al4V substrate was prepared by sol-gel technique using Ca(NO3)24H2O, P2O5, hexafluorophosporic acid (HPF6) as the starting materials and the fluorine-introducing reagent. The results show that the sol-gel derived fluorapatite/hydroxyapatite coating has a good in vitro behavior in the simulated body fluid, and has a better stability in the citric acid modified phosphate buffer solution than hydroxyapatite coating. The sol-gel derived coatings are composed of nano apatite crystallites.
