发明名称 FOERFARANDE FOER FRAMSTAELLNING AV SILICIUM UR KVARTS OCH KOL I ELEKTRISK UGN
摘要 A process for producing silicon in which a reaction mixture consisting, on the one hand, of hot-pressed briquettes of silicon dioxide (quartz) and carbon and, on the other hand, of granular quartz are introduced into an electric furnace and reacted so that silicon carbide is produced from the agglomerates and the silicon carbide then reacts with the quartz which fuses from the granular quartz to produce elemental silicon.
