The chemical composition of silicon metal 441 mainly includes silicon (Si), iron (Fe), aluminum (Al), calcium (Ca), etc.
The specific contents are as follows:
Silicon (Si): The content is not less than 98.5%, which is the main component.
Iron (Fe): The content is not more than 0.4%.
Aluminum (Al): The content is not more than 0.4%.
Calcium (Ca): The content is not more than 0.1%.
Size requirements: The size is usually required to be silicon metal 10-100mm or 2-25mm, which can also be adjusted according to customer needs.
Appearance requirements: It is silver-gray lump, the surface should be clean, without obvious inclusions, rust spots and oil stains, etc.
In actual applications, different industries and customers may have some special requirements for the quality of silicon 441, such as restrictions on certain trace elements.
