A surfactant and ligand assisted wet chemical method was employed for the preparation of nanostructuremagnesium oxide with a high specific area and sphere-like nanoparticles. The influenceof surfactants and ligands on the crystallite size and morphology of MgO was studied using variousparameters. X-ray diffraction XRD studies show that the crystallite size varies. Observations withField Emission Scanning Electron Microscopy FFSEM and Transmission Electron MicroscopyTEM show that the ligands and surfactants strongly affect the size of nanostructure. We synthesizedless than 15 nm using a PVA 72000 surfactant in the presence of EDA and 4-methyl morpholineligands, 15 - 40 nm with a PVA 72000 surfactant in the presence of oleic acid, and more than40 nm with a PEG 6000 surfactant. The effects of several process parameters, such as surfactant,ligand and solvent, were examined.
