Synthesis and Characterisation of hydroxyapatite Nanopowders by hydrothermal method

الملخص EN

In this study, a hydrothermal method of synthesizing Hydroxyapatite (HAp) by heating a precipitate, formed by mixing Ca (NO3) 2.

4 H2O and (NH4) 2 HPO4 with distilled water, in hydrothermal reaction 200 0C for 24 hrs has been described.

After that, the characterisation techniques were used such as X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Dynamic Light Scattering (DLS), Selected Area of Electron Diffraction (SAED) and Energy-Dispersive X-ray spectroscopy (EDX).

Results indicated that the pure (HAp) nanostructure with uniform morphologies, controllable size, nano-dispersion and narrow-size distribution in diameter were synthesized successfully, and the synthesized powders can be used extensively in medicine, dentistry for implant synthesis and for scientific research
