The search for synthetic materials with bioactive, osteoconductive, and biocompatible characteristics is becoming highly desirable for various biomedical applications. Hydroxyapatite (HA), a biomaterial, is an inorganic ceramic that closely resembles the mineral apatite, primarily found in human bones and teeth. Its characteristics, such as biocompatibility, cell adhesion, bioactivity, and degradation, are fundamental for potential applications as a biomaterial, particularly in bone regeneration [1][2]. Thus, this study aims to synthesize and characterize hydroxyapatite using the precipitation technique by the wet method, with the use of acid/base reagents. In order to analyze the chemical elements and microstructure of the obtained material, techniques such as X-Ray Diffraction (XRD), Rietveld Refinement, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive Spectroscopy (EDS) were employed. The XRD results showed peaks of hydroxyapatite and calcium oxide. The FTIR analysis revealed vibration bands of carbonates (CO32-) and phosphates (PO43-), characteristic of the material. SEM indicated irregular morphologies with different shapes and forms. Additionally, EDS analysis showed the presence of calcium, phosphorus, and oxygen, and through this result, the Ca/P molar ratio was determined to be 1.60. The characterizations indicated the presence of B-type carbonated hydroxyapatite, suggesting a nanometric form with good crystallinity and density. Furthermore, it is suggested that the hydroxyapatite obtained in this study has great potential to be applied as a biomaterial.
