A., Courbevoie, France Duration: February 2001 – September 2004

3 HA molecule : Ca 10 (PO 4 ) 6 OH 2 Projection in the (001) base plan of the hydroxyapatite unit cell (hexagonal structure) How difficult is to deposit CaPs? - very complex molecules

4 a = 19.68(1) Å b = 9.50(1) Å c = 6.832(5) Å = 90.21(8)° = 92.52(9)° = 108.32(8)° Electron microscopy of OCP revealing nano-crystalline domains embedded in an amorphous matrix X-ray diffraction patterns are in agreement with an amorphous-poor crystalline structure. OCP presence is confirmed by the shoulder around 4.7° of 2θ, corresponding to the (100) reflection of OCP, and by the broad peak centered around 32-33° of 2θ. Amorphous layer Cristalline OCP a) b) c) Titanium XHRTEM image at the interface of the sample thermally treated at 180°C: c) FFT of the surrounded domain from a); b) enlargement and filtered image of the domain surrounded in a)
