| Abstract: | Nanocrystalline nickel oxide has been
prepared via thermal decomposition of precursors obtained using two methods,
sol-gel process and homogeneous precipitation. The precursors and the oxide
obtained by calcination are characterized by various analytical techniques such
as powder X-ray diffraction, thermal gravimetric analysis, FT-IR spectroscopy, surface
area measurements, scanning electron microscopy, transmission electron
microscopy and magnetic measurements. The crystallite size of nickel oxide
prepared from homogeneous precipitation method is ~ 2 nm whereas that of the nickel
oxide prepared from sol-gel process is about 19 nm. The nanocrystalline NiO
samples obtained by both the methods exhibit superparamagnetic behavior. |
