Metallic silicon, also known as industrial silicon or crystalline silicon, is usually produced by reducing silicon dioxide with carbon in an electric furnace. Its main use is as an additive for non-ferrous alloys and as a starting material for producing semiconductor silicon and organic silicon.
In my country, metallic silicon is usually classified according to the content of the three main impurities of iron, aluminum and calcium. According to the percentage of iron, aluminum and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101. (About the source of the numbering of metallic silicon: the first and second codes represent the percentage of iron and aluminum, and the third and fourth digits represent the calcium content. For example, 553 represents the iron, aluminum and calcium content of 5%, 5% and 3%; 3303 represents the iron, aluminum and calcium content of 3%, 3% and 0.3%)
