Abstract
Hydroxyapatite (HAp) was produced through the hydrothermal conversion of agro-industry byproducts (eggshells). Commercial calcium dibasic phosphate (CaHPO4.2H2O) and lime (CaO), obtained from direct calcining of the eggshells, were the reactants in the synthesis scheme employed. X-ray powder diffraction and scanning electron microscopy confirmed the HAp as the main phase present in the final products.
