Product Overview
Silicon Metal 2202 represents the premium tier of metallurgical-grade silicon, offering exceptional purity for demanding applications. The designation "2202" indicates maximum impurity limits of 0.2% Iron, 0.2% Aluminum, and 0.02% Calcium – delivering a minimum silicon content of 99.6%. This ultra-pure grade is essential for high-performance aluminum alloys, specialty silicones, advanced refractories, and semiconductor feedstock applications where trace impurities cannot be tolerated.
Chemical Composition
| Parameter | Guaranteed Maximum | Typical Value | Test Method |
|---|---|---|---|
| Silicon (Si) | ≥ 99.6% | 99.7 – 99.8% | ICP-OES / Gravimetric |
| Iron (Fe) | ≤ 0.20% | 0.12 – 0.18% | ICP-OES |
| Aluminum (Al) | ≤ 0.20% | 0.10 – 0.16% | ICP-OES |
| Calcium (Ca) | ≤ 0.02% | 0.005 – 0.015% | ICP-OES |
| Phosphorus (P) | ≤ 0.003% | 0.001 – 0.002% | Spectrometry |
| Sulfur (S) | ≤ 0.003% | 0.001 – 0.002% | Combustion method |
Available Particle Sizes
| Size Code | Particle Range | Best Suited For |
|---|---|---|
| Lump | 10 – 100 mm | Induction furnace charging, bulk alloying |
| Small lump | 5 – 25 mm | Small furnaces, ladle addition |
| Granular | 1 – 5 mm | Continuous feeding systems, briquette pressing |
| Fine | 0 – 1 mm | Powder metallurgy, slurry preparation |
| Custom | Any range ±2 mm | Please specify your requirements |
Packaging, Shipping & Logistics
Packaging Options
| Type | Net Weight | Container Load (20' FCL) | Advantages |
|---|---|---|---|
| Jumbo bag | 1000 kg / 1250 kg | 20–25 MT | Easy forklift handling, stackable |
| Small bag + master carton | 25 kg bag | 1000 bags / 25 MT | Manual handling friendly, palletized |
| Bulk in container | Loose loading | 25–27 MT | Lowest cost, requires hopper |
| Drum | 200 kg (steel or fiber) | 100 drums / 20 MT | Weather-protected, smaller quantities |
Palletization & Storage
All bags are double-layer woven polypropylene with an inner PE liner (moisture barrier)
Heat-sealed to prevent dust leakage and oxidation
Palletized with shrink wrap for warehouse storage (1 MT per pallet)
Store in dry, covered area – silicon metal can slowly oxidize in humid conditions

FAQ
Q: What particle size should I order for aluminum alloy production?
A: For most aluminum melting operations:
- Induction furnaces (≥5 tons) → 10–100 mm lump
- Crucible furnaces (small batches) → 5–25 mm small lump
- Ladle addition → 1–5 mm granular
- Master alloy production → 0–1 mm fine or 1–3 mm granular
Q: Do you provide free samples before I place a bulk order?
A: Yes. We offer a free 1–2 kg sample of Silicon Metal 2202 (standard 10–100 mm lump or your requested size). You only pay the shipping cost. The sample includes a full Certificate of Analysis. This allows you to verify quality in your own laboratory or production trial.
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 20 metric tons (one 20-foot container). For smaller quantities (5–15 MT), we can arrange LCL (less than container load) shipment, but freight costs will be higher per ton. Sample orders (1–2 kg) are exempt from MOQ.
Q: What quality documentation do you provide?
A: Every shipment includes:
- Certificate of Analysis (COA) – Batch-specific, showing Si, Fe, Al, Ca, P, S, C
- Packing List – Quantity, weight, package count
- Material Safety Data Sheet (MSDS) – Handling and safety information
- Bill of Lading – Shipping document
- Commercial Invoice – Commercial transaction record
Optional (at buyer's cost):
- Third-party inspection report (SGS, Bureau Veritas, Intertek)
- Certificate of Origin
- Insurance certificate
