Nickel oxide nanoparticles were prepared via molten salts and microwave assisted synthesis from nickel nitrate and the parameters of obtained nanopowders were compared. NiO nanoparticles with crystallite size in the range of 6-8 nm have been prepared by combining microwave assisted treatment of Ni(NO3)2 and urea solution with calcination at 300-320 oC. Molten salts (NaNO3-NaCl) ensured direct formation of NiO from Ni(NO3)2.6H2O and salts mixture at 350 oC but crystallite size of the particles reached 51-69 nm.
