【 摘 要 】

Analysis of reduction smelting of silicon showed the formation of a secondary stable silicon carbide. The possibility of lading fresh charge to the lower horizons of the furnace tank was shown, which excludes the formation of stable silicon carbide. The initial temperatures of the interaction of silica and silicon carbide, obtained using various carbonaceous reducing agents, are determined.
