| Abstract: | Nanostructured
materials are of considerable interest in both fundamental as well as applied
research areas due to their unique physical and chemical properties and also
promising applications in nanodevices. In recent years, variety of
nanomaterials have been prepared by using different methods. Molten nitrates
and particularly nitrate eutectic melts, because of low melting temperatures,
are frequently used as nonaqueous solvents for studying a number of chemical
reactions and preparation of materials. Nano size nickel oxide (about 15 nm)
has been prepared by the reaction of nickel sulphate in NaNO3 - KNO3
eutectic melt. The specific reaction conditions for the preparation of nano
size NiO have been specified using TG and DTA techniques. NiO produced has been
characterized by X-ray powder diffraction (XRD) and scanning electron
microscopic (SEM) techniques. Probable reaction mechanism for the reaction has
also been proposed. |
