Characterization of the hydroxyapathite obtained from chicken egg shell applied in bioceramics

This study aims to dispose of eggshells in an environmentally correct way, contributing to environmental preservation. The study is carried out on the characterization of chicken eggshell to obtain hydroxyapatite, it was found that both the shell and the calcined powder of the chicken egg are rich in calcium, carbon and oxygen. In addition, the shell has a porous morphology with carbon tangles. With regard to the morphology of the calcined powder, it can be noted that the calcium oxide particles have similar shapes and a regular surface. Thus, the results showed that eggshell can be a potential source of calcium for obtaining hydroxyapatite.
