Abstract: Hydroxyapatite(HA) was synthesized by using CaCO3 and CaHPO4·2H2O as raw materials under hydrothermal condition. The relation between ratio of raw materials, hydrothermal temperature, reaction time and the resultant phases, changes of granularity, crystal appearance were studied by using SEM and XRD. This HA synthesized has a good crystal appearance, good dispersity, its end plane granularity is less than 100 nm.

Key words: hydrothermal synthesis, Hydroxyapatite(HA), namo partical
