METHOD AND APPARATUS FOR PREPARING HIGH PURITY METALLIC SILICON |
摘要 |
High-yield preparation of high-purity metallic silicon is performed by subjecting a stream of oxides of silicon (e.g. in an aerosol) to reaction heat in the presence of a mixture of oxides of silicon and a material of the group including carbon and metallic carbide. Preferably, silicon oxide produced by the reaction is scavenged from exhaust gas leaving the reaction chamber, re-condensed, and returned to the reaction chamber. |
