Ferro Silicon Nitride Powder Export Certification Guide (FeSiN Supplier China)
What Certifications Are Required for Exporting Ferro Silicon Nitride Powder?
Exporting refractory grade FeSiN powder requires a combination of quality assurance certifications, chemical safety documentation, and third-party inspection reports. These documents ensure compliance with customs clearance, industrial procurement standards, and end-user furnace safety requirements.
Typical required certifications include:
ISO 9001 Certification (factory quality system control)
SGS / BV / Intertek Inspection Report (third-party quality verification)
MSDS (Material Safety Data Sheet) (chemical handling and transport safety)
COA (Certificate of Analysis) (chemical composition confirmation)
REACH Compliance (EU market) or equivalent chemical registration documents
Packing List + Commercial Invoice + Certificate of Origin (COO)
These documents are essential for buyers searching for a reliable ferro silicon nitride powder manufacturer China or silicon nitride iron powder exporter.
Technical Parameters of FeSiN Powder (Refractory Grade)
| Item | Specification |
|---|---|
| Product Name | Ferro Silicon Nitride Powder |
| Grade | Metallurgical / Refractory Grade FeSiN Powder |
| Nitrogen (N) | 25% – 32% |
| Silicon (Si) | 48% – 55% |
| Iron (Fe) | Balance |
| Particle Size | 0–1 mm / 1–3 mm / fine powder 200 mesh |
| Appearance | Gray-black powder / granular |
| Application | Blast furnace refractory additive, taphole clay additive FeSiN |
This refractory grade FeSiN powder is widely used as a blast furnace refractory additive powder to improve erosion resistance and thermal shock stability.
FeSiN Powder vs Other Refractory Additives
| Material | FeSiN Powder | Ferrosilicon (FeSi) | Silicon Nitride (Si₃N₄) |
|---|---|---|---|
| Nitrogen Content | High (25–32%) | None | Very High |
| Furnace Stability | Excellent | Medium | Excellent |
| Cost Efficiency | Balanced | Lower | Higher |
| Application | Taphole clay, blast furnace | Steel deoxidation | Advanced ceramics |
| Performance in Refractories | Strong bonding phase formation | Limited | High purity but expensive |
Conclusion: FeSiN offers a cost-performance balance, making it the preferred blast furnace refractory powder additive in modern steelmaking systems.
