Nickel Powders were prepared from an aqueous nickel chloride solution containing 40 vol% of ethanol with hydrazine hydrate using the conventional and microwave hydro-thermal synthetic method. It was shown that microwave non-thermal effect and synthetic conditions affect the formation of nickel powders by means of X-ray diffractometry, scanning electron microscopy, thermal gravimetric analysis and X-ray photoelectron spectroscopy analysis. Compared with the conventional hydrothermal synthetic method, shorter reduction time, smaller particle size, and more unifrom distribution of of particle size were obtained in the microwave hydrothermal synthetic method due to the non-thermal effect of microwaves.
