This study concerns the results of the development of hydroxyapatites, in the field of Biomaterials, we mainly encounter ceramics, especially the uses and developments of bioactive ceramics based on calcium phosphate: hydroxyapatite (HAP), there are therefore uses of hydroxyapatite (HAP) in dental implants and filling materials and in orthopedic surgery. The objective of this work was initially, it was a new field of research that deals with more advanced ceramic materials used in Biomaterials and Nanotechnologies, the second objective was to develop hydroxyapatite of high purity from natural resources for their application. We can consider that this double objective has been achieved since on the one hand we have characterized these hydroxyapatites; on the other hand, this material is synthesized from several routes. Several techniques were used; including X-ray diffraction (XRD), scanning electron microscopy coupled with EDX microanalysis (SEM-EDX), differential thermal and gravimetric analyzes (DTA-TGA) and finally the Fourier transform infrared (FTIR) and X fluorescence (XRF).
Key words: Hydroxyapatite, DRX, IR, Synthesis, Characterization, Porosity, Osteoconduction.
