Metallic Silicon Production Process
The production of metallic silicon employs the carbothermal method, which involves smelting quartzite and carbonaceous reducing agents in an arc furnace. The silicon produced by this method has a purity of 97% to 98%, which is generally suitable for metallurgical purposes. If a higher grade of silicon is required, further refining to remove impurities is necessary to achieve a purity of 99.7% to 99.8%.
The smelting of metallic silicon from quartz sand includes several steps: the preparation of quartz sand blocks, the preparation of furnace charges, and the smelting process in an arc furnace.
