Abstract :
Hydroxyapatite (HA,Ca10(PO4)6(OH)2), that the principal mineral component of the bone tissue, has remarkable precursor of growth properties in the porous structure sort with strongly interconnected pores. The interconnection of the pores is an essential condition assuring high quality of bone implants. We suggest the experimentation of a silicon nanotubes structure (SiNT) as support to enhance the growth of a high quality HA. We propose a model obtaining a silicon nanotubes structure, by silicon atoms adsorption, from vapour phase, in the pores of AlPO4 (AFI) zeolite. A collection of 3D interconnected nanotubes of the deposited silicium can be obtained after matrix removal.
