Abstract :Hydroxyapatite, Ca5insert ignore into journalissuearticles values(PO4);3OH was prepared via the reaction of calcium hydroxide with orthophosphoric acid or between calcium nitrate and diammonium hydrogen phosphate at different PH 1 S and temperatures of aging. The crystalline phases were detected by XRD. The molar Ca/P ratio was found to be approximately 1.72. The specific surface areas m2/g were also calculated. The Transmittance Electron Microscope, insert ignore into journalissuearticles values(TEM); indicate that the hydroxyapatite powder insert ignore into journalissuearticles values(HA); produced was prismatic in shape with uniform size. The IR spectra of the prepared powder were given. The solubility of the synthesized powder, bulk density in g/cm3, water abrorption % and apparent porosity % were also given. The Scanning Electron Microscope, insert ignore into journalissuearticles values(SEM); shows the agglometration in the grains and its fine nature.
Keywords : HA, P TCP, TEM and SEM
