Abstract

Oppfinnelsen gjelder fremstilling av høyrenhets silisium som et grunnmaterial for fremstilling av for eksempel krystalline silisiumsolceller. SiCl4 blir konvertert til Si metall ved å kontakte gassformig SiCl4 med flytende Zn, hvorved det oppnåes en Si holdig legering og zinkklorid som blir separert. Den Si holdige legeringen blir deretter renset ved en temperatur over kokepunktet av Zn. Denne prosessen krever ikke kompliserte teknologier og bevarer den høye renheten av SiCl4 mot sluttproduktet når den eneste reaktanten er Zn som kan bli oppnådd i veldig høye renhetskvaliteter og som blir kontinuerlig resirkulert.
