ABSTRACT:
A carbide former is introduced into briquettes in the production of silicon in an electric-arc low-shaft furnace to improve the trapping of silicon oxide rising in the furnace and increase the silicon yield. The carbide former can be calcium, magnesium or aluminum, preferably in the form of the silicate and most advantageous is magnesium silicate.
