SILICON CARBIDE AS A RAW MATERIAL FOR SILICON PRODUCTION |
摘要 |
What is described is a process for the production of silicon via the carbothermic reduction of silicon dioxide in which silicon carbide is fed as the total reductant source or as a portion of the reductant input. The process also includes recovery and recycle to the furnace of silicon monoxide and other silicon-containing materials from the by-produced gases from the furnace to maximize raw material efficiency. Finally, the process includes the recovery of energy value from the combustible by-produced gases. |
