Abstract: Hydroxyapatite, the primary bone substitute, has gained increased interest of researchers. The primary purpose of this study was to synthesize hydroxyapatite nanoparticles through the utilization of eggshell waste and two distinct phosphate sources ((NH4)2HPO4 and Na3PO4.12H2O). The chemical precipitation approach was chosen for this study, then the final products were named HAP-1 and HAP-2. Following this, the synthesized particles were investigated using XRD, FTIR, and SEM methods. The crystallite size of the synthesized materials was also determined by employing the Debye-Scherrer equation. The synthesis of the HAP granules was confirmed through XRD analysis, and the crystallite sizes of HAP-1 and HAP-2 were calculated to be 37.79 nm and 28.7 nm, respectively. The SEM results also indicates that the powders had a spherical-like morphology, but were highly agglomerated due to their nanoscale dimensions.
