Available Grades
V2O5 98% Flake
Commonly used as feedstock for ferrovanadium production, selected according to the reduction process and acceptable impurity limits of the final ferrovanadium alloy.
V2O5 99% Flake
Provides higher vanadium pentoxide concentration and tighter published impurity limits, suitable for downstream processes requiring higher-purity vanadium feedstock.
Size and Form
Commercial dimensions include fused flake form with up to approximately 5 mm thickness and maximum dimensions of approximately 50-55 mm.
Applications
Ferrovanadium Manufacturing
V2O5 flakes serve as the principal vanadium-bearing feed material for ferrovanadium production, charged into electric furnaces with other raw materials.
Vanadium Alloy Production
Used for producing vanadium-aluminum and other vanadium-bearing master alloys.
Chemical Applications
Serves as an industrial vanadium intermediate in chemical processing and catalyst-related applications.
Technical Advantages
Flake V2O5 is denser and produces less dust than fine powder, making it particularly suitable for metallurgical charging applications according to commercial technical references.
Procurement Specifications
Buyers should confirm the following parameters:
- Product grade and V2O5 content
- Impurity levels (Fe, Si, P, S, As)
- Alkali-metal limits
- Flake size and dimensions
- Quantity and application
- Destination and packing requirements
- Required documentation
Quality Assurance
Typical documentation includes Certificate of Analysis (COA), Safety Data Sheet (SDS), packing list, batch information, and inspection reports when required. Actual batch composition should be verified against agreed specifications.
Packaging Options
Commercial packaging includes 200-250 kg drums and 1 MT bulk bags. Final packaging selection depends on shipment and handling requirements.
