FIELD: metallurgy.
SUBSTANCE: charge consists of dioxide of silicon in form of amorphous silicon dioxide, as carbon containing reducer - soot and additionally - gel of silicic acid at following ratio of components, wt %: amorphous silicon dioxide 36-44, gel of silicic acid 9-17, soot 47-55.
EFFECT: increased output of silicon with upgraded chemical purity applicable for production of solar silicon both in ore-thermal furnaces and in high temperature furnaces of boiling bed.
