Controllable self-assembly of mesoporous hydroxyapatite

- The additive amount of MAP and hydrothermal temperature were important factors for the pore structure and pore size.
- With the increasing additive amount of MAP, a broader size distribution was exhibited and the degree of crystallinity of samples was decreased.
- Between 90 °C and 120 °C, HAp with lamellar mesoporous structure was formed and kept stable. However, when temperature rose up to 150 °C, the lamellar mesoporous structure collapsed and disappeared.
