Summary:Size-controlled synthesis of hydroxyapatite nanorods was carried out by chemical precipitation method using citric acid, sodium dodecyl sulphate, and sodium dodecylbenzene sulphonate as organic modifiers and starting from calcium nitrate, phosphoric acid, and ammonia solution. The crystallinity of the resultant hydroxyapatite increased with increasing the autoclaving temperature. The particle sizes of the resultant HAP nanorods varied with the presence of the different structured organic modifiers and the synthetic temperature. The interaction between the anions of the modifiers and the hydroxyapatite crystallites controlled the crystal growth.
