Metal silicon 441, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon is a non-metallic element, gray, metallic color, hard and brittle. The content of silicon accounts for about 26% of the mass of the earth's crust; the atomic weight is 28.80; the density is 2.33g/m3; the melting point is 1410C; the boiling point is 2355C; and the resistivity is 2140Ω.m.
Metal silicon 441 is a product smelted by quartz and coke in an electric heating furnace. The content of the main component silicon is about 98% (in recent years, the silicon content of 99.99% is also included in metal silicon), and the remaining impurities are iron, Aluminum, calcium, etc. That metal silicon 441 is mainly used as an additive for non-ferrous alloys, and has a wide range of uses. It is mainly used for metallurgical deoxidation, aluminum alloys, and the production of polycrystalline silicon and single crystal silicon. It is also used to make high-purity semiconductors, high-temperature resistant materials, optical fiber communication materials, and organosilicon compounds. It is widely used in aerospace, electronics, construction, transportation, energy, chemicals, textiles, food, light industry, medical, and agricultural industries. and many more.
The above is the basic product description of the metal silicon 441 shared by the editor. I will share it here. I hope it will be helpful to everyone. In the later stage, if you have any product problems related to metal silicon 441, you can leave a message to the editor on the website in time.
