Influence of alumina substrates open porosity on calcium phosphates formation produced by the biomimetic method.

We evaluated the influence of the open porosity of alumina (AlO) substrates on the phase formation of calcium phosphates deposited onto it surface. The AlO substrates were prepared with different porosities by the foam-gelcasting method associated with different amounts of polyethylene beads. The substrates were coated biomimetically for 14 and 21 days of incubation in a simulated body fluid (SBF).
