    摘要: A process for producing high purity silicon characterized by the employment of an electric arc heater into which a silicon halide is injected together with a metal reductant such as an alkali metal or an alkaline-earth metal which are reacted together by projecting them tangentially into a reaction chamber to cause the formation of liquid silicon and a gaseous metal halide salt which are separated in a suitable manner such as centrifugally or by condensation.

    摘要: A process for converting silicon intermediates to high purity silicon by an arc heater characterized by the steps of preliminarily reacting gaseous silicon intermediate, such as a silicon halide, with a metal reductant, such as sodium, to form preliminary reaction products including small solid silicon particles and droplets of salt of the metal reductant, at temperatures below the boiling point of the metal reductant, subsequently heating the reaction products to temperatures above said boiling point in an arc heater chamber to convert the reaction products to droplets of silicon to merge and form larger silicon droplets, and thereafter separating the mixture of silicon droplets and salt vapor.

    摘要: A method for melting machine chips characterized by a preheating zone, a prereducer zone, and a melting zone the latter of which is heated by an arc heater through which a reducing inert gas is introduced into the communicating zones, whereby metal chips entering the preheating zone move through the subsequent zones in counterflow to the reducing gas flow.
