| Abstract: | The mixture of CaHPO4 @ 2H2O and CaCO3 was ground in an aqueous system under appropriate con-ditions to investigate the mechanochemical reaction for the synthesis of crystalline hydroxyapatite (HA) powder.Hydroxyapatite of high crystallinity powder including trace Cat0 ( PO4 ) 6 CO3 ( OH ) and Ca9 HPO4 ( PO4 ) 6 OH canbe synthesized by mechanical activation without further thermal treatment at a high temperature. The synthesisreaction during the grinding process was almost completed within 1 h. The as-ground powder exhibits a particledistribution of 20-100 nm in size with a spherical or rodlike morphology. The composition and degree of crys-tallinity of the mechanochemical synthesized hydroxyapatite powders were coincident with the cement-typehydroxyapatite. |
