Abstract

Amorphous calcium phosphate nanoparticles were synthesized by mixing aqueous solutions of Ca(NO₃)₂ and (NH₄) ₂-HPO₄. Then the particles were matured with sodium bis-(2-ethylhexyl) sulfosuccinate (AOT) at various temperatures. Rod-shaped hydroxyapatite (HAp) nanoparticles were formed at maturation temperature ≥40 °C. These results indicate that addition of AOT not during the particles synthesis but during the maturation at more equal critical temperature is a key to form the rod-shaped HAp nanoparticles using AOT.
