V2O5 99.5% High-Purity Flakes
High-purity V2O5 flakes are used where lower impurity levels are critical, with 99.0% guaranteed and 99.5% typical V2O5 content.
Size and Form
V2O5 flakes are particularly suited for metallurgical applications due to their physical handling characteristics.
- Thickness: up to approximately 5 mm
- Maximum flake dimensions: approximately 50 × 50 mm to 55 × 55 mm
- Form: fused flakes
- Color: dark grey, brown or yellow-orange depending on material and source
Applications
- Vanadium Alloy Production: Feedstock for producing ferrovanadium and other vanadium-bearing master alloys
- Chemical Processing: Intermediate for production of vanadium compounds and chemical materials
- Catalyst Applications: Used in catalyst systems and chemical processing
- Metallurgical Applications: Vanadium-bearing feedstock for steel and alloy production
Technical Considerations
V2O5 serves as a concentrated vanadium oxide intermediate. Grade selection depends on required V2O5 content, downstream alloy composition, impurity limits (Fe, Si, P, S, alkali metals), flake size, furnace charging conditions, and chemical processing requirements.
Quality and Documentation
Common purchasing documents include Certificate of Analysis, Safety Data Sheet, Packing List, batch information, and inspection reports when required. For high-purity material, the COA should identify V2O5 and relevant trace impurities.
Packing
Commercial V2O5 flakes are supplied in steel drums (200–250 kg) or bulk bags (1,000 kg). Final packing is confirmed according to shipment quantity, handling requirements, and destination regulations.
Frequently Asked Questions
What are V2O5 flakes used for?
Mainly used as vanadium-bearing raw material for ferrovanadium, vanadium alloy production, chemical processing, and selected industrial applications.
What V2O5 grades are available?
Common commercial flake grades include 98% and 99%, while high-purity products reach approximately 99.5% typical V2O5 content.
What is the difference between 98%, 99% and 99.5% V2O5?
The principal difference is V2O5 concentration and degree of impurity control, with 99.5% associated with higher-purity products and tighter chemical requirements.
Are V2O5 flakes suitable for catalyst production?
V2O5 is used in catalyst applications, but catalyst producers may require powder or specific particle characteristics rather than standard metallurgical flakes.
