Hydroxyapatite(HAP) nanoparticles were successfully prepared from the biowaste chicken eggshells and phosphoric
acid solution by chemical precipitation methods. The structures of HAP were characterized in terms of the X-ray
diffraction (XRD), scanning electron microscope (SEM), and Fourier transform-infrared (FT-IR) spectroscopy. The
effect of temperature on the crystallinity and lattice parameters of prepared HAP was monitored by X-ray powder
diffraction. Energy dispersive X-ray analysis revealed that the HAP had a Ca/P molar ratio of about 1.65 and 1.69
for as prepared and sintered HAP at 1200oC (1 hour), respectively. The temperature dependence on the electrical
conductivity of sintered HAP nanoparticle was investigated. Furthermore, dielectric properties such as dielectric constant and dielectric loss as a function of frequency for the sintered HAP were also studied.
