The sol-gel method was used for obtaining Ni(OH)2 and NiO. For structural characterization of the material we used XRay Diffraction (XRD). Morphological structures and chemical composition were examined by scanning electron microscopy (SEM.). The results obtained, it was found that the average particle size of the Ni(OH)2 is about 15.8 nm and the thermal treatment for calcination at 350° C obtain NiO particle size is 48.5 nm. The result of DSC analysis of the precursor product showed that the proper calcination temperature was 350°C.
