✦ Synopsis

Hierarchically nanostructured hydroxyapatite (HA) hollow spheres assembled from nanorods have been successfully synthesized using CaCl 2 , NaH 2 PO 4 , and potassium sodium tartrate via a solvothermal method at 200 °C for 24 h in water/N,N-dimethylformamide (DMF) mixed solvents. The ratio of water to DMF plays a key role in the formation of hierarchically nanostructured HA hollow spheres. The potassium sodium tartrate was used as a chelating ligand and a template molecule in the synthesis and self-assembly of HA nanorods. The products were characterized by X-ray powder diffraction, and field-emission scanning electron microscopy
