company news about Features of metal silicon 553

Good silicon metal 553 in content characteristics: the conventional national standard silicon metal 5533 requires iron content of 0.5%, aluminum content of 0.5%, calcium content of 0.3%. In terms of content, the silicon content of silicon metal should be as high as 98.5%, which has a good effect in steel making and deoxidation. When purchasing Silicon metal 553, you can also request a sample from the silicon metal manufacturer for laboratory analysis. Good silicon metal 553 should meet the content requirements.

553 Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive in nonferrous alloys. Silicon is a non-metallic element, gray, metallic, hard and brittle. The content of silicon is about 26% of the mass of the crust; Atomic weight 28.80; Density is 2.33g/m3; The melting point is 1410C; Boiling point 2355C; The resistivity is 2140 ω.m. 553 kinds of silicon metal additional products: including silicon powder, edge silicon, black silicon, silicon slag and so on. Among them, silica powder, also known as silica powder, microsilica powder or silica powder, is widely used in refractory materials and concrete industry. Among them, 553 silicon metal refers to silicon metal iron content is less than or equal to 0.5%, aluminum content is less than or equal to 0.3%, calcium content is less than or equal to 0.3%; 331 silicon metal said iron content is less than or equal to 0.3%, aluminum content is less than or greater than 0.3%, calcium content is less than or less than 0.1%, and so on, due to customary reasons, 2202 is also abbreviated to 220, said calcium is less than or equal to 0.02%, 2 beginning of silicon metal is usually called chemical silicon.
