Palmer Deposition of Bio-Integration Ceramic Hydroxyapatite by Pulsed-Pressure MOCVD Using a Single Liquid Precursor Solution Chemical Vapor Deposition 16
Hydroxyapatite films have been prepared by pulsed-pressure MOCVD by single source liquid precursor using calcium lactate and tri-methyl phosphate. The precursor mixture, deposition temperature and precursor concentration to produce calcium phosphate with the stoichiometry of hydroxyapatite were investigated. Fully amorphous hydroxyapatite was produced with very interesting topology with spherical morphology. The deposition formed a solid, adherent, conformal layer on the biomedical grade titanium alloy substrates with chaotic spherical and nebulous structures growing normal to the substrate. The number and profile of the spherical structures increased with temperature and precursor concentration.
