Effect of Surfactant in Formation of Hydroxyapatite Nano-Rods under Hydrothermal Conditions
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 w...

متن کاملEffect 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...
متن کاملOctacalcium phosphate as a precursor in biomineral formation.
What are biominerals and how are they formed? It is usually assumed: (i) that the prototype for most apatitic biominerals is hydroxyapatite (OHAp), Ca5(PO4)3OH; and (ii) that the OHAp structure has been modified by the presence of impurity ions and vacancy defects in specific OHAp lattice sites. The usual answer, at least implicitly, to the second question is that the apatitic mineral is formed...
متن کاملA New Mixture of Nano-structure of Potassium-incorporated Hydroxyapatite/β-tricalcium Phosphate/calcium Pyrophosphate
The new triphasic potassium−substituted hydroxyapatite (KHAP), β−tricalcium phosphate (β−TCP), and calcium pyrophosphate (CPP) proportions using easy sol−gel method were synthesized. The prepared powders was characterized by X–ray diffraction (XRD), Fourier transform infrared (FTIR), Differential thermal behavior (DTA) analysis, Energy Dispersive X–ray Analysis (EDXA), and Brunauer–Emmett–Telle...
