Abstract

Die Erfindung betrifft ein Gesamtverfahren zur Herstellung von reinem Silicium, das als Solarsilicium geeignet ist, umfassend die Reduktion eines gereinigten Siliciumoxids mit einer oder mehreren reinen Kohlenstoffquellen, wobei das gereinigte Siliciumoxid, das als in wässrige Phase im Wesentlichen gelöstes Siliciumoxid gereinigt wurde und bezogen auf das Siliciumoxid einen Gehalt an anderen polyvalente Metallen, oder auch Metalloxiden, von kleiner gleich 300 ppm, bevorzugt kleiner 100 ppm, besonders bevorzugt kleiner 50 ppm, erfindungsgemäss kleiner 10 ppm an den anderen Metallen aufweist, und vorteilhaft durch Gelbildung im Alkalischen gewonnen wird. Ferner betrifft die Erfindung eine Formulierung enthaltend einen Aktivator sowie die Verwendung gereinigten Siliciumoxid zusammen mit einem Aktivator zur Herstellung von Silicium.
