Arc heater with silicon lined reactor

摘要

An arc heater system for producing high purity silicon characterized by the use of an arc heater into which a silicon halide is injected together with a liquid metal reductant, such as an alkali metal, which are reacted together by projecting them into a reaction chamber to cause the formation of liquid silicon, and the walls containing the system being provided with cooling jacket means for preliminarily heating the reactants.
