| 摘要 |
Producing silicon, preferably solar silicon, comprises reducing silicon dioxide with carbon in an arc furnace. The parts of the furnace or the electrodes are made of a graphite material, which in turn are obtained from a carbon material. The carbon material is obtained by pyrolysis of at least one carbohydrate, preferably at least one sugar. An independent claim is also included for a graphite molded part, preferably molded part of the arc furnace, preferably graphite electrode, which is doped with silicon oxide, preferably silicon dioxide and/or silicon carbide. |
