Specifically, we highlight the class of ceramic biomaterials, as example the hydroxyapatite. This is a calcium phosphate similar to the one found in bones and can be used as a bone substitute in the orthopedics and dentistry areas. This type of phosphate can be obtained from the eggshell, being a material discarded in the environment and considered a waste, but it is a source rich in calcium. The calcium present in the eggshell is in the form of calcium carbonate, in the proportion of about 40% of the powdered product, and from this the hydroxyapatite can be obtained. From the above, the objective of this work was to obtain hydroxyapatite from chicken eggshell. Initially the shells were transformed into calcium oxide and later into hydroxyapatite by the wet method. After obtaining the material, it was characterized by X-ray diffraction through the Reitiveld refinement technique and by Scanning Electron Microscopy, where it was possible to identify the presence of the crystalline phase of Hydroxyapatite Ca10 (PO4) 6 (OH) 2 and its topography. According to the obtained results it can be concluded that the methodology was effective and the powder has potential to be used in the area of biomaterials. In defense of the maintenance of environmental conditions, several segments of society have demonstrated, including professionals in the field of biology and materials engineering, with responsibility to avoid and promptly act to establish the most appropriate conditions and to seek and propose the use of materials solutions to environmental problems.
