Abstract:
Hydroxyapatite bioceramics are essential minerals for the human body, their production in synthetic form requires steps and precise care as it is a material for application in the human body. Therefore, the objective of this study is to synthesize hydroxyapatite, using eggshell as a source of calcium. The characterizations by XRD and FTIR resulted in hydroxyapatite and calcium oxide phases, and CO32-, PO43- and OH- bands, respectively. In addition to the characterizations, analyzes by Rietveld refinement confirmed the majority presence of Hydroxyapatite, around 90.4%, and the GOF of 1,20, in agreement with the mathematical parameters proposed by Rietveld. Therefore, it was possible to obtain hydroxyapatite wet using eggshell residue.
