چکیده

hydroxyapatite (ha) nano-rods with uniform morphology and controllable size have been successfully synthesized in the presence of cationic and non-ionic surfactants by a hydrothermal method. (nh4) 2hpo4 and ca(no 3)2.4h2o were used as the phosphorus and calcium sources, respectively. the composition of synthesized powders was characterized using x-ray diffraction, and fourier transform infrared spectrometer and morphology of the resulting powders were examined by scanning electron microscopy. results revealed the as- prepared ha nano-rods have a typical diameter of about 60-80 nm and an average aspect ratio of about 10-12, which indicates that the mixture of cationic and non-ionic surfactants acts as a soft template to regulate the nucleation and crystal growth of ha. also effect of hydrothermal temperature was studied on the system.

Effect of chelating agent on Hydroxyapatite morphology under hydrothermal process

Citrate was used as chelating or morphology regulating agent in this study. In the presence of regulating agent a two-dimensional monetite phase evolved into  three-dimentional hydroxyapatite microspheres with an average diameter of 4 µm. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) studies revealed the importance of Ca/citrate ratio in regulating the particle m...

Surfactant-assisted hydrothermal synthesis of hydroxyapatite nanopowders.

Rod-like hydroxyapatite nanoparticles (n-HAp) with a highly ordered nanostructure were prepared by hydrothermal synthesis from calcium chloride, and phosphoric acid, as calcium and phosphorus sources, respectively. Various surfactant families such as cationic (CTAB), anionic (SDS) and nonionic (Triton X-100) were used as regulators of the nucleation and crystal growth. The synthesized nanopowde...
