Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-iron-based alloys. Metallic silicon is a product smelted from quartz and coke in an electric furnace. The main component silicon content is about 98% (in recent years, 99.99% Si content is also included in metallic silicon), and the remaining impurities are iron and aluminum. , calcium, etc.
