PROCESS FOER SMAELTNING AV KISEL UNDER ANVAENDNING AV EN PLASMA SAASOM VAERMEKAELLAE |
摘要 |
What is disclosed is a process for preparing silicon using a gas plasma as a heat source. The process comprises (a) generating a gas plasma in a reactor utilizing a transferred arc plasma configuration in which a minimum of gas is utilized to form a plasma; (b) feeding silicon dioxide and a solid reducing agent directly into the reactor and to the plasma; (c) passing the plasma gas, the silicon dioxide, and the solid reducing agent into a reaction zone of the reactor; (d) recovering molten silicon and the gaseous by-products. |
