Product type
Silicon metal is a high-purity form of silicon that is primarily used in the production of silicon-based alloys and as a raw material in various industrial applications. It is produced through the reduction of silica in electric arc furnaces, resulting in a metallurgical grade silicon that is typically over 98% pure. Silicon metal is essential in the manufacturing of semiconductors, solar cells, and aluminum alloys.
| Purity | 98% to 99.99% |
| Form | Lumps, granules, or powder |
| Melting Point | 1414°C (2577°F) |
| Density | 2.33 g/cm³ |
| Chemical Composition | Silicon with minimal impurities such as iron and aluminum |
When purchasing silicon metal, buyers should consider the desired purity level, as higher purity grades are required for semiconductor applications. It is also important to specify the form of silicon metal needed, whether in lumps, granules, or powder. Additionally, buyers should inquire about the supplier's certifications and the availability of material safety data sheets (MSDS) to ensure compliance with safety standards.
