摘　　要：Nanocrystal carbonated hydroxyapatite was prepared by lecithin-controlled chemical precipitation in synthetic body fluid （SBF）. The reactant was aged and heated at 850℃ for crystallization. The morphology and microstructure of the carbonated hydroxyapatite were investigated using transmission electron microscope （TEM）, X-ray diffraction （ XRD ） and FTIR. The experimental results demonstrate that the shapes of carbonated hydroxyapdtite particles display spheres with the average size of 20- 28 nm, and carbonated hydroxyapatite contained carbonate ions, similar to mineral of bone tissues.Nanocrystal carbonated hydroxyapatite was prepared by lecithin-controlled chemical precipitation in synthetic body fluid （SBF）.
