The purpose of this work is to determine one of the most important mechanical properties of brittle materials, the hardness. Our work material is called hydroxyapatite (HAP), in this case, using chicken egg shells as precursor. Once considering the experimental parameters of force and time of the indentation, the Vickers microhardness measurements were obtained for both for HAP, synthesized from chicken egg shells and commercial hydroxyapatite for comparison purposes. The microstructural characterization of the materials, as well as their specimens, has been performed by the microscope scanning, x-ray diffraction and thermogravimetric analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
