| Abstract：The Ni(OH) 2 precursor was prepared by a homogeneous precipitation method from urea and NiCl 2·6H 2O. Then the nanometer NiO was obtained with annealing at high temperature. Thermo decomposition presses of Ni(OH) 2 precursor, microstructure, morphology, and the particle size of nanometer NiO were investigated by means of TG DTA, X ray powder diffraction(XRD), and scanning electron microscopy(SEM). |
| Key words：homogeneous precipitation; nanometer; precipitant |
