Metallurgical grade silicon refers to industrial-grade silicon raw material obtained through ore smelting, with a silicon content ranging from 95% to 99%. Its advantages are as follows:
- High purity and stability: Metallurgical-grade silicon typically has a purity of over 99.9%, making it suitable for producing high-purity silicon products. Its chemical properties are highly stable and it does not readily react with other substances.
- Excellent processability: Metallurgical silicon has low hardness, making it easy to process into various shapes and sizes, suitable for manufacturing a wide range of silicon products.
- Wide range of applications: Metallurgical silicon can be used to produce solar panels, semiconductors, glass, ceramics, and other products.
- Environmental friendliness: The production process of metallurgical silicon is relatively environmentally friendly, generating minimal waste gas, wastewater, and slag, with minimal environmental impact.
- Applications in the metallurgical industry: Metallurgical silicon is commonly used as an additive in iron alloys, enhancing the quality of steel production and improving the steel's toughness, corrosion resistance, and fatigue resistance.
- Applications in the electronics industry: Metallurgical silicon is one of the basic raw materials for manufacturing semiconductor materials. After chemical purification, it can be processed into monocrystalline silicon.
