Abstract

Hydroxyapatite, an important bioceramic was synthesized in the bulk form and developed as a coating by a sol–gel route using alcoholic precursor. The bioactive coating was developed on bio-inert α-alumina and yttria stabilized zirconia substrates. The apatite phase began to form after the heat treatment of the precursor at 500 °C for 10 min. The complete crystallization of the apatite was obtained at 800 °C heat treatment for 10 min. The phase composition of the bulk and the coatings was identified by FT-IR spectroscopic and powder X-ray diffraction (XRD) techniques. Surface morphology was determined by scanning electron microscopy. The study indicates different surface textures for the powder and for the coatings on α-alumina and yttria stabilized zirconia substrates.
