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

ABSTRACT: We evaluated the influence of the open porosity of alumina (Al₂O₃) substrates on the phase formation of calcium phosphates deposited onto it surface. The Al₂O₃ 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). Scanning electron microscopy characterisation and X-ray computed microtomography showed that the increase in the number of beads provided an increase in the open porosity. The X-ray diffraction and infrared spectroscopy showed that the biomimetic method was able to form different phases of calcium phosphates. It was observed that the increase in th
