Activation of aluminium metal to evolve hydrogen from water

The method of aluminium metal activation by liquid eutectics Ga–In (70:30) and Ga–In–Sn–Zn (60:25:10:5) is developed. Subsequent dispersion of the obtained specimens up to a particle size of > 0.5 mm leads to the drastic interaction of aluminium powder and water with evolving hydrogen. In the present work the oxidation rate of activated aluminium and water is investigated depending on eutectic composition, reaction temperature, and powder particle size. chanism of the main eutecticʹs components influence on the reacting ability of aluminium is discussed.
