A process for the preparation of nickel titanate, which comprises adding an aqueous solution containing ions of titanium and nickel, to an aqueous alkaline solution containing hydrogen peroxide. The resulting precipitate is recovered and heated at a temperature of 850 oC to give nickel titanate. The samples were then analyzed using a series of techniques including X- ray diffraction (XRD), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and Thermo gravimetry (TG). The results indicated that nickel titanate nanopowders with particle size less than 100 nm could be obtained after calcination of precipitate at 850 oC.
