Silicon metal is a critical raw material used in various industries, including aluminum production, solar energy, electronics, and steelmaking. Understanding its chemical composition is essential for procurement decisions, quality assessment, and industrial applications. As Beifang Alloy, a leading ferroalloy supplier, we provide high-quality silicon metal tailored to different industry needs.
Silicon metal is primarily composed of silicon (Si) with varying levels of impurities. The main chemical elements found in silicon metal include:
| Element | Typical Composition (%) |
|---|---|
| Silicon (Si) | 98.5% – 99.99% |
| Iron (Fe) | 0.1% – 0.5% |
| Aluminum (Al) | 0.1% – 0.5% |
| Calcium (Ca) | 0.01% – 0.1% |
| Carbon (C) | Trace amounts |
| Phosphorus (P) | < 0.01% |
The purity level of silicon metal varies depending on the grade, with standard grades like 553, 441, 3303, and 2202 commonly used in different industries.
Silicon metal is a key material for multiple industries, and its demand continues to grow. Some of the major applications include:
When purchasing silicon metal, several factors should be considered:
🔹 Purity Level: Higher purity (e.g., 2202, 3303) is required for electronics and solar industries, while lower purity (e.g., 553, 441) is sufficient for aluminum and steelmaking.
🔹 Particle Size: Silicon metal is available in different sizes, such as lumps (10-100mm), granules (3-10mm), or powder (0-3mm), depending on the application.
🔹 Impurity Levels: Check for Fe, Al, and Ca content based on specific industrial requirements.
🔹 Packaging & Logistics: Ensure secure packaging (e.g., 1MT jumbo bags) and reliable transportation for international shipments.
