Metallic silicon is also the raw material for ultrapure silicon in the electronics industry. Silicon is used in large quantities to smelt ferrosilicon alloy as an alloying element in the steel industry and as a reducing agent in the smelting of many metals. Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon. Silicon is the raw material for ultrapure silicon in the electronics industry. Electronic devices made of ultrapure semiconductor single crystal silicon have the advantages of small size, light weight, good reliability and long life.
The classification of metallic silicon is usually based on the content of the three main impurities of iron, aluminum, and calcium contained in the metallic silicon component. According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.
