Introduction: Hydroxyapatite is a bio ceramic that has chemical and physical similarities to the minerals of bones and teeth. Hydroxyapatite is a biocompatible material utilized in some medical application such as bone repair, tissue regeneration and reinforcement material due to its good mechanical and biological properties. It can be extracted from natural materials such as coral and eggshell. The content of CaCO3 (calcium carbonate) in chicken eggshells reaches 94% which makes it a potential candidate for producing hydroxyapatite. Utilization of egg shells can also contribute to the reduction of agricultural waste. Methods: Hydroxyapatite nanoparticles were synthesized from eggshell by hydrothermal method then processed by ball-milling to form nano particle size. Hydroxyapatite crystal structure identified by X-ray Diffraction (XRD) and the functional group of hydroxyapatite was confirmed by Fourier-transform infrared spectroscopy (FTIR). Results: Eggshell Based Hydroxyapatite Nanoparticles can be extracted by hydrothermal method in 243,4 nm particle size measured by PSA analysis. XRD analysis showed crystalline phase identified the hydroxyapatite with small impurities such as silica. FTIR analysis confirmed the synthesized hydroxyapatite with eight main peak of wave number identified the functional groups of hydroxyapatite. Conclusion: Eggshell Based Hydroxyapatite Nanoparticles was good candidate of biomaterial for reinforcement material or other application, but other strategy needed to eliminate the impurities especially for tissue regeneration material. © 2023 UPM Press.
