Initial stage for preparing alumina supported metal catalysts according to a scheme, essentially reducing harmful wastes, is discussed. Preparation method is based on a direct interaction of pretreated metallic aluminum with water. Diffusion phenomena are shown to be the core of aluminum activation by metallic In-Ga alloy. A method for estimating the coefficient of liquid gallium bulk diffusion into the grains of various poly crystal aluminium alloys is suggested.
