ABSTRACT
Hydroxyapatite (HAp) was successfully produced from recycled eggshell, seashell and phosphoric acid. The phases obtained
depended on the ratio of calcined eggshell/ seashell to phosphoric acid, the calcination temperature and the mechanochemical activation
method (ball milling or attrition milling). The HAp structures were characterized by X-ray diffraction, scanning electron microsopy and
infrared spectroscopy. Attrition milling was more effective than ball milling, yielding nanosize, homogenous and pure Hap
