Hydrothermal synthesis and crystal growth mechanism of hydroxyapatite nanorods
Hydroxyapatite (HA) nanorods were synthesized by hydrothermal process using anhydrous CaCl<sub>2</sub> and (NH<sub>4</sub>)<sub>2</sub>HPO<sub>4</sub> as raw materials, urea was used as a homogeneous precipitation agent; hexadecyltrimethy ammonium brom...
