Synthesis of hydroxyapatite particles in catanionic mixed surfactants template
Different morphologies of nano hydroxyapatite particles, Ca10 (PO4) 6 (OH) 2 (HAP) are
prepared by precipitation method using CaCl2 and H3PO4 (water phase) and the mixture of
cationic surfactant cetyltrimethyl ammonium bromide (CTAB) and anionic one sodium
dodecyl sulfate (SDS) as template. The mixture of these surfactants in two regions of cationic-
rich and anionic-rich form the various aggregations as template. The results show that by
changing the ratio of cationic to anionic surfactant in the mixture the morphology of the nano …

Different morphologies of nano hydroxyapatite particles, Ca10(PO4)6(OH)2 (HAP) are prepared by precipitation method using CaCl2 and H3PO4 (water phase) and the mixture of cationic surfactant cetyltrimethyl ammonium bromide (CTAB) and anionic one sodium dodecyl sulfate (SDS) as template. The mixture of these surfactants in two regions of cationic-rich and anionic-rich form the various aggregations as template. The results show that by changing the ratio of cationic to anionic surfactant in the mixture the morphology of the nano HAP can be controlled. The nano structure of products is studied by the means of X-ray diffraction (XRD), Fourier transmission infrared spectrometer (FT-IR) and scanning electron microscopy (SEM). With this system we could synthesize nano particles of hydroxyapatite with high crystallinity and least agglomeration.
