    Investigations on Synthesis, Structural, Morphological and Dielectric Properties of Manganese Oxides Nanoparticles
    Author(s): Sagadevan SSagadevan S

    Manganese oxides (MnO2) nanoparticles were synthesized using a co-precipitation technique. The as prepared nanopowder was used for further characterization. The size, structure and morphology of MnO2 nanoparticles were characterized by X-ray diffraction (XRD) and SEM. The crystallite size of the synthesized MnO2 nanoparticles was obtained from X-ray diffraction study using Debye-Scherer formula and it was found to be 22 nm. The surface morphology of prepared MnO2 nanoparticles was analyzed by scanning electron microscope. The optical properties were analyzed using UV-studies. Dielectric studies were carried out for the pelletized sample of MnO2 nanoparticles. The dielectric properties of MnO2 nanoparticles were studied in the different frequency range of 50Hz-5MHz at different temperatures. .. Read More»
