Grey With Metallic Luster Ferro Vanadium Lump

Aluminothermic (Thermite) Process：Primary method for high-grade ferrovanadium (50–80% V). Raw Materials: Vanadium pentoxide (V₂O₅) or vanadium-rich slag. Aluminum powder (reducing agent). Iron scrap or iron oxide (to adjust Fe content). Fluxes (e.g., lime, fluorite) to control slag formation.

Process Steps: Mix V₂O₅, aluminum, iron, and fluxes in a refractory-lined reactor. Ignite the reaction (externally triggered). Exothermic reaction generates temperatures up to 2,500°C, reducing V₂O₅ to metallic vanadium. Molten ferrovanadium settles at the bottom, while slag (Al₂O₃, CaO) floats on top. Separate the alloy and cool it into ingots. Advantages: High purity (low carbon, sulfur, and phosphorus).
Suitable for producing FeV80 (80% V) and FeV50 (50% V). Disadvantages: High cost of aluminum and limited scalability for very large batches.
