Metal Silicon 553

Metal silicon is also called crystalline silicon or industrial silicon. The content of the main component silicon is about 98%. Its main use is as a reducing agent in the smelting of various metals. Industrial silicon grades, such as 553,441, 331, 2202, etc., refer to the sub-categories with a silicon content greater than or equal to 98.5%, which are divided into three impurity contents of iron, aluminum and calcium (in order).

Metal silicon 553 can be divided into oxygen-passing metal silicon and oxygen-impermeable metal silicon in products. Oxygen-passing silicon is silicon oxide, which can remove impurities such as Ca, and oxygen-passing silicon is pure silicon raw material.

Only by fully understanding the characteristics of metal silicon 553 can we buy better metal silicon 553 products among many metal silicon 553 manufacturers. 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.
