Notes:
This paper reports synthesis of hydroxyapatite nanoparticles by three precipitationmethods. Homogeneous aqueous solution of Ca(NO3)2 and H3PO4 was used as precursor solution,and NH3•H2O was precipitator. Calcium deficient hydroxyapatite nanorods were obtained byadding the precipitator into precursor solution, near stoichiometric hydroxyapatite nanoparticleswere derived from adding precursor solution into the precipitator, and smaller hydroxyapatitenanoparticles were prepared by adding precipitator and precursor solution simultaneously into areaction vessel. The stoichiometry of hydroxyapatite was mainly affected by pH at precipitationreaction process. The crystal size and shape of hydroxyapatite particles was related to Ostwaldripening. The stoichiometry and morphology of hydroxyapatite nanoparticles can be controllable byselecting suitable coprecipitation process
