摘要：

Sol gel technology offers an alternative technique for producing a bioactive surface for improved bone attachment. Hydroxyapatite was synthesized using the sol-gl technique with alkoxide precursors and the solution allowed to age up to 7 days. Coatings produced on MgO substrates were characterised by differential thermal analysis, thermal gravimetric analysis, X-ray diffraction and atomic force microscopy. It was found that, similar to the wet method of hydroxyapatite synthesis, an ageing time is required to produce a pure hydroxyapatite phase.
