Metallic silicon is a very important industrial product that can be used in many industries such as steelmaking, cast iron, aluminum (aviation, aircraft, and automotive parts production), and silicon optoelectronic devices. Known as the "salt" of modern industry. Metallic silicon is a product produced by smelting quartz and coke in an electric heating furnace. The main component silicon content is about 98%. The remaining impurities are iron, aluminum, calcium, etc. Produce metal silicon blocks in an electric heating furnace using quartz and coke as raw materials. Quartz undergoes oxidation-reduction and becomes molten silicon. After cooling, it will turn into a solid as we see it. The original silicon metal block is very large.
