In the present paper, Nano-Hydroxyapatite (n-HAp) is synthesized from Indian Hen (Busra breed) and Hybrid Hen eggshell waste using chemical precipitation methods. The principal objectives of this research are to synthesize natural HAp from eggshell waste and comparing with commercial available Hydroxyapatite (HAp) as reference sample (NnanoXIM-Hap-202).
Analytical methods were used to characterize n-HAp and HAp including Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Differential Scanning Calorimetry (DSC) and Thermogravimetry-Differential Thermal Analysis (TG-DTA). Calcinations of eggshell waste at 850 to 900°C yielded HAp with a calcium/phosphorus ratio of 1.71 to 1.75.
A comparative analysis with a reference sample (commercially available HAp) revealed that the synthesized HAp exhibited similar structural and chemical properties, with slight variations in their morphological and thermal characteristics.
