Fluoridated hydroxyapatite films on glass and Ti alloy substrates were prepared by sol-gel technique using hexafluorophosphoric acid (HPF 6) as a fluorine-introducing reagent.

A process of preparing phosphorus pentafluoride was put forward: first, mesneproduct(hexafluorophosphoric acid) was prepared from phosphorus pentoxide and anhydrous hydrogen fluoride; second, phosphorus pentafluoride was acquired after dealing with the hexafluorophosphoric acid.
