Metallic silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive for non-iron based alloys. Silicon metal is made of quartz and coke in the electric furnace smelting products, the content of the main component silicon element is about 98% (in recent years, the content of Si 99.99% is also included in silicon metal), the remaining impurities are iron, aluminum, calcium and so on.
Â
Â
The classification of silicon metal is usually classified by the content of the three main impurities of iron, aluminum and calcium contained in the silicon metal composition. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.

Specifications | Content(%) | Particle size (mm) |
553 | Fe≤0.5%,Al≤0.5%,Ca≤0.3% | 10-70 |
441 | Fe≤0.4%,Al≤0.4%,Ca≤0.1% | 10-70 |
421 | Fe≤0.4%,Al≤0.2%,Ca≤0.1% | 10-70 |
3303 | Fe≤0.3%,Al≤0.3%,Ca≤0.03% | 10-70 |
2202 | Fe≤0.2%,Al≤0.2%,Ca≤0.02% | 10-70 |
97Si | 1.2%≤Fe≤2.0%,0.2≤Ca≤1.5% | 10-70 |

Industrial silicon metal is often used as a substitute for steel mills when iron silicon prices rise;
The chemical silicon metal is mainly used in the production of solar energy and electronics;
Industrial and chemical silicon metals can be processed into silicon powder for the production of different silica sols and other refractory products.
