Magnesium ethoxide complex Mg(OEt)_2-x(acac)_x was synthesized by means of the electrochemical method. Its ethanol solution was hydrolyzed to give nano-sized xerogel Mg(OEt)_2-x-y(OH)_y(acac)_x. The latter was then heated at 500℃ for 2 h to give nano-sized MgO powder. The precursor, xerogel and MgO powder were characterized by FT-IR, TG-DTA, XRD and TEM. The precursor and xerogel contain acac^- group. The latter should be calcinated beween 470~500℃. The MgO powder is of mono disperse structure with the size of 15~20 nm.
