Characteristics of metal silicon 553


 1. Product Features:

The characteristics of good metal silicon 553 in terms of content: the regular national standard metal silicon 553 requires the content of iron element to account for 0.5%, aluminum element to account for 0.5%, and calcium content to account for 0.3%. In terms of content, the silicon content in metal silicon should be as high as 98.5%, which has a good effect in steelmaking and deoxidation. When purchasing metal silicon 553, you can also ask for samples from metal silicon manufacturers for laboratory analysis. A good metal silicon 553 should meet the content requirements.


553 metal silicon, 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. Additional products of 553 metal silicon: including silicon micropowder, edge silicon, black silicon, silicon slag, etc. Among them, silica micropowder is also called silica fume, micro-silica fume or silica fume, which is widely used in refractory materials and concrete industries. Among them, 553 metal silicon means that the metal silicon contains iron less than or equal to 0.5%, aluminum content less than or equal to 0.5%, calcium content less than or equal to 0.3%; 331 metal silicon represents iron content less than or equal to 0.3%, aluminum content less than or equal to 0.3%, calcium content Less than or equal to 0.1%, and so on, due to customary reasons, 2202 is also abbreviated as 220 to represent calcium less than or equal to 0.02%, and the metal silicon at the beginning of 2 is generally called chemical silicon.
