Synthesis, Characterization and Electrical Properties of Hydroxyapatite Nanoparticles from Utilization of Biowaste Eggshells

다국어 초록 (Multilingual Abstract)

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 1.69for 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.
