A method for synthesizing monocrystalline alumina nanofibers by controlled liquid phase oxidation of a melt including molten aluminum. The method comprises two stages. During the first stage, metallic aluminum is melted and various additives are introduced into the melt. During the second stage, the alumina nanofibers are synthesized from the resulting melt in the presence of oxygen. In one or more embodiments, the inventive method is performed in a reactor. The reactor is designed to provide the heating and to enable melting of metallic aluminum. In addition, the reactor is designed to maintain a sustained temperature of between 660° C. and 1,000° C. When the additives are introduced into the molten aluminum, it is desirable to provide steady and uniform the stirring of the melt. To this end, the reactor may be provided with a stirring mechanism.
