Silicium aus der Schmelze: Elektroreduktion oder -oxidation von pelletiertem SiO2-Pulver (Bild links) oder seiner Mischungen mit anderen Metalloxid-Pulvern in geschmolzenem CaCl2 ergibt reines Si-Pulver (Bild rechts) bzw. die entsprechenden Si-Legierungen. Dieses einfache Verfahren hat neben der reduzierten CO2-Emission den Vorteil, dass der Energieverbrauch unter 13 kWh pro kg Si liegt.
