Synthesis and characterization of NiO Nanoparticles using egg white method

NiO nanoparticles have been synthesized by chemical method using Egg white. Phase formation and magnetic properties of NiO nanoparticles were characterized by using TG/DTA, XRD, RAMAN and VSM. Magnetic parameters such as remnant (M-R) and saturation magnetization (M-S) of NiO nanoparticles sintered at 700 degrees C were 0.007 and 1.04 emu/g, respectively. ESR measurement was also carried out to identify the origin of magnetic nature and the measured effective g-factor of NiO nanoparticles is 2.29. Morphological characterization has been done on obtained NiO nanoparticles by FE-SEM and TEM analysis. The chemical composition of NiO nanoparticles was identified by energy dispersive X-ray spectroscopy studies. Dielectric properties of sintered NiO disk were examined at room temperature as a function of frequency.
