Preparation of biological hydroxyapatite coating by ethanol based sol-gel technique.
AbstractThe ethanol - based sol-gel method was used for synthesis of nanocrystalline hydroxyapatite. The HA coating has been prepared on alumina ceramic substrate by dipping into ethanol sol-gel suspension ofCa(NOj).4H20 and (NH_,)2 HPO4. To achieve better biocompatibility and excellent mechanical performance of prostheses, HA coating is often fabricated on surface of bone substitute implant
