Abstract

Bioceramics fulfil a unique function as biomedical materials. The development of biomaterials and manufacturing techniques has broadened the diversity of applications within the human body. In this work, hydroxyapatite was successfully produced by using recycled eggshell, seashell and phosphoric acid. The observed phases on the powder synthesis process were dependent on the mixing ratio (wt.%) of the calcined eggshell/seashell and phosphoric acid, the calcination temperature and the method of the mechanochemical activation (ball milling, attrition milling). Elaboration processes of the hydroxyapatite (HAp) have been developed and compared of the HAp from different raw materials (eggshell, seashell) and processing method (ball milling, attrition milling milling). The structures of the HAp were characterized by X-ray diffraction and scanning electron microsopy.
