OBTAINING SILICON INTERACTION OF SILICON OXIDE AND SILICON CARBIDE WITH THE NECESSITY IN PRESENTING A SECOND CARBON SOURCE

摘要

The application describes a method for producing silicon by chemical conversion of silicon oxide at an elevated temperature with the addition of silicon carbide and, if necessary, a second carbon source to the reaction mixture. The application also describes a composition that can be used in the implementation of the method according to the invention. The basic idea of the invention is to use silicon carbide as a reaction initiator and / or reaction accelerator in the production of silicon or, alternatively, in approximately equimolar amounts for the production of silicon.
