Contemporary methods for silumin preparation are reviewed. Prospects of preparing silumin using amorphous silica are connected, first, with a high yield of silicon production waste; second, with a return for their industrial use; and, third, with deterioration of the ecological situation adjacent to slurry field of the territory. A thermodynamic possibility is established for reducing silicon dioxide in molten aluminum. Different methods are studied for adding SiO2 particles into molten aluminum. It is determined that the most effective method is exhibited by adding particle to melt in a semisolid state.
