In this work, a combination of methods for HAp synthesis is investigated. Fish bones were calcined at 900oC between 4h and 12h, followed by milling in a high-energy ball mill, by 2h and 4h at 300rpm. The obtained material was characterized by using techniques such as laser granulometry, X-ray diffraction, scanning electron microscopy (SEM) and atomic absorption spectroscopy. The performed analysis permitted us to obtain the Ca/P ratio, the morphology and the phase structure of hydroxyapatite particles powder.
