The meaning of various grades of metallic silicon:
Each grade of silicon metal has its own specific meaning, for example, 553/441/2202/3303, etc., which means that the silicon content is greater than or equal to 98.5%, divided into three types of impurities: iron, aluminum, and calcium (in order) Of subcategories.
Among them, metallic silicon 553 represents that the industrial silicon contains iron less than or equal to 0.5%, aluminum content is less than or equal to 0.5%, and calcium content is less than or equal to 0.3%;
Metallic silicon 441 Industrial silicon means iron content is less than or equal to 0.3%, aluminum content is less than or equal to 0.3%, calcium content is less than or equal to 0.1%, and so on, due to customary reasons.
Metallic silicon 2202 is also abbreviated as 220, which means that calcium is less than or equal to 0.02%. The industrial silicon at the beginning of 2 is generally called chemical silicon.
