Abstract
A silicon prodn. process involves (i) generating a gas plasma in a reactor, using a transferred arc and a minimum of plasma-forming gas (ii) feeding silicon dioxide and solid reductant directly into the plasma (iii) passing the plasma gas and the feed into a reaction zone of the reactor and (iv) recovering molten silicon and gaseous by-prods. from the reaction zone.
