The classification of Silicon metal is usually based on the proportion of the three main impurities of iron, aluminum, and calcium contained in Silicon metal. According to the content of iron, calcium, and aluminum in Silicon metal, Silicon metal can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101. (For example, the iron content in 553# Silicon metal is not more than 0.5%, the aluminum content is not more than 0.5%, the calcium content is not more than 0.3%, and so on)
| Garde | si | Fe | Al | Ca |
| ≥ | ≤ | |||
| 1101 | 99.79% | 0.1% | 0.1% | 0.01% |
| 2202 | 99.58% | 0.2% | 0.2% | 0.02% |
| 3303 | 99.37% | 0.3% | 0.3% | 0.03% |
| 441 | 99.1% | 0.4% | 0.4% | 0.1% |
| Silicon metal Size: 10-30mm; 30-50mm; 50-100mm or according to customer requirements |
