Abstract:
Hydroxyapatite (HA), an inorganic ceramic biomaterial, presents itself as a promising and active bone substitute in this scenario, as it presents characteristics similar to the mineral apatite, found in human bones and teeth. Thus, the aim of this work is to synthesize and characterize synthetic hydroxyapatite, using chicken eggshell residue as a source of calcium. The analysis of the egg shell was carried out using X-ray Diffraction (XRD) and Fourier Transform Spectroscopy (FTIR) techniques. The characterization of the hydroxyapatite powder was performed by X-Ray Diffraction (XRD), Fourier Transform Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). The results for eggshell revealed the presence of absorption bands of hydroxyl groups and carbonates and phases corresponding to calcium hydroxide and calcium oxide. The HA sample showed vibration bands of hydroxyl, carbonate and phosphate groups, and hydroxyapatite and calcium oxide phases. SEM analysis indicated irregular morphological formations with dimensional variations. The EDS semiquantitatively revealed percentages of Oxygen, Phosphorus and Calcium. According to the results, type B hydroxyapatite was obtained using eggshell residue, which was also a good source of calcium in this study.
