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.
