Uses And Properties Of Silicon Metal 441

Silicon metal 441 is mainly used in the manufacture of aluminum alloys. The color of the metal silicon 441 is gray, and the surface has a metallic luster and is very hard. The main use of metallic silicon is as an additive in non-ferrous alloys. The main use of metal silicon 441 is to produce aluminum alloys and semiconductor materials.

The main use of silicon metal is as an additive to non-ferrous alloys. The silicon content in the earth's crust is 27.7%, which is the second largest element in the earth's crust, and the most abundant elements in the earth's crust - oxygen and silicon - combine into silicon dioxide SiO2, which accounts for 87% of the total mass of the earth's crust. Silicon is a non-metallic element, gray, metallic, hard and brittle. The atomic weight is 28.80; the density is 2.33g/m3; the melting point is 1410℃; the boiling point is 2355℃; the resistivity is 2140Ωm. Semiconductor silicon is a high-purity silicon metal, in the form of polysilicon and single crystal silicon, used in the production of semiconductor devices.
