Abstract
Hydroxyapatite is a typical bio-material as an implant for bone and teeth. In this work, the nano-meter size hydroxyapatite precursor was synthesized through the chemical precipitation method. Effect of the heat-treatment of hydroxyapatite nano-meter size precursor on particle size, crystalline size and crystallinity was studied. Heattreatment was done at 550, 700 and 900° in air atmosphere. Futhermore, the sintering behavior of this nanocrystalline hydroxyapatite after the heat-treatment was investigated. The microstructure of these hydroxyapatite precursor and heat-teated hydroxyapatite was observed by FE-SEM and TEM. The synthesis parameters were investigated in order to synthesize the nanometer-size hydroxyapatite powder.
