Basic description of metal silicon 441
Metal silicon 441 is also called crystalline silicon or industrial silicon, which is mainly used as an additive for non-ferrous alloys. Silicon is a non-metallic element, gray, metallic, 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; 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, silicon content of 99.99% is also classified as metal silicon), and the remaining impurities are iron, aluminum, calcium, etc. Metal silicon 441 is mainly used as an additive for non-ferrous alloys. It has a wide range of uses. It is mainly used for metallurgical deoxidation, aluminum alloys, and the production of polysilicon and monocrystalline silicon. It is also used to make high-purity semiconductors, high-temperature resistant materials, optical fiber communication materials, organic silicon compounds, etc. It is widely used in aerospace, electronics, construction, transportation, energy, chemical industry, textile, food, light industry, medical, agriculture and other industries. Etc.
