Abstract
Submicron nickel powders were prepared in aqueous solution through a thermal-reduction process. The effect of reaction conditions on the morphology and particle size of Ni powders are discussed. X-ray diffraction and SEM were employed to characterize the products. SEM showed that the average particle size was 0.3 ㎛ having spherical shape with narrow size distribution at optimum condition. The reduction rate of Ni^(2+) was above 90%.
