Abstract

Two nano-hydroxyapatite materials being similar in morphology but different in surface structure (crystalline and including a 1 to 2 nm thick amprphous layer) have been studied by high resolution transmission electron microscopy and FTIR spectroscopy in vacuum and using in situ CO and H20. These materials have been shown to have similar stoichiometry and carbonate content. The properties of surface cationic sites and the structure of water adlayers are considered in detail.
