Abstract
Det beskrives en fremgangsmåte for fremstilling av høyren silisium der det fremstilles et silisium ved å redusere et halogenert silisium representert ved formel (1) med aluminium. I denne metoden har det aluminium som benyttes som reduksjonsmiddel en renhet på ikke mer enn 99,9 vekt-%. SiHnX4-n (1) I denne formel betyr n et helt tall fra 0 til 3, og X er et halogen valgt blant F, Cl, Br og I. I denne forbindelse er aluminiumets renhet den rest som oppnås etter reduksjon av den totale vektprosentmengde av jern, kobber, gallium, titan, nikkel, natrium, magnesium og sink i aluminiumet.
