X-ray diffraction patterns of the calcium phosphate materials as tested.
Notes: Diffraction patterns are shown on a common diffraction angle scale. It can be seen that the micron sized materials and sintered nano-HA were predominately crystalline, while nano-TCP, nano-TCP/HA, nano-HA, and human bone mineral were poorly crystalline.
Abbreviations: HA, hydroxyapatite; TCP, tri-calcium phosphates.
