Hydrothermal Synthesis of Hydroxyapatite – Polymer Composite Materials
The hydrothermal syntheses of hydroxyapatite and polymer composite materials were studied. The apatite precursor slurry was prepared by agitating a mixture of CaCO3 and CaHPO4·2H2O, and 3 kinds of polymeric fibers were added. The mixture was treated under hydrothermal conditions at 180 °C for 5 hours. The XRD patterns of the products showed that the products were well-crystallized hydroxyapatit...
متن کاملSurfactant-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...
متن کاملSynthesis of Hydroxyapatite Nanostructure by Hydrothermal Condition for Biomedical Application
In this investigation, hydroxyapatite (HAp) nanostructure with uniform morphologies, controllable size, nano-dispersion and narrow-size distribution in diameter has been synthesized successfully by low-temperature hydrothermal process, and the as-synthesized powders were characterized by energy-dispersive X-ray spectroscopy, scanning electron microscopy, high-resolution transmission elect...
متن کاملHydrothermal Synthesis of Aligned Hydroxyapatite Nanorods with Ultra-High Crystallinity
Hydroxyapatite nanorods aligned with ultrahigh crystallinity and high-yield were successfully synthesized through a hydrothermal approach. In this experiment, a new composition of cetyltrimethylammonium bromide ((CH3(CH2)15N+(CH3)3Br-) was designated as CTAP)/Ca(NO3)2/(NH4)2HPO4/NaOH and distilled water under hydrothermal condition, to synthesize single crystalHAp nanorods with diameter of 20 ±...
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...
