Hydroxyapatite (HA) particles synthesized by hydrothermal treatment of octacalcium phosphate (OCP) particles were characterized in detail and the reaction mechanism was discussed. The calcium-deficient HA particles were firstly formed and their compositions gradually closed to the stoichiometric composition with reaction progress. While their compositions closed to the stoichiometric composition, split of plate-shaped HA particles into smaller strips and subsequent crystal growth of HA particles were observed. The [001] direction of synthesized HAwas parallel to the [001] direction of starting material of OCP. The hydrothermal treatment of OCP particles is useful for synthesis of plate-shaped HA particles with different morphologies and compositions.
