The objective of this work is the preparation of hydroxyapatite by femur dromedary bone heat treatment. The treatment was carried out at temperatures up to 1000 °C, and the powders obtained were characterized by Fourier Transform Infrared Spectroscopy, X-ray diffraction, X-ray fluorescence spectrometry, and laser granulometry. The results show that the extracted powder corresponds to a hydroxyapatite whose crystallinity increases with the increase of the calcination temperature. The removal of the organic matter from 600 °C leads to a white powder of nanoporous structure. The chemical analysis of the calcined powder shows the presence of the major calcium and phosphorus elements with atomic ratio Ca/P = 1.62. The powder also contains ions’ trace such as sodium, magnesium strontium, and zinc. The dromedary bone can be considered as a new source of hydroxyapatite whose applications can …
