V2O5 flake is a vanadium-bearing metallurgical raw material primarily used for ferrovanadium production and vanadium alloy manufacturing. The resulting ferrovanadium is subsequently used as a vanadium addition in steelmaking and alloy production.

Product Grades
V2O5 98% Flake
V2O5 98% is a widely documented metallurgical flake grade commonly used as the vanadium-bearing feedstock for ferrovanadium production. The downstream smelting process determines the acceptable Fe, Si, P, S and alkali-metal levels.
V2O5 99% Flake
V2O5 99% provides a higher minimum vanadium pentoxide content and generally tighter impurity limits than common 98% flake. The complete chemical specification should be compared with the buyer's ferrovanadium production requirements rather than selecting the grade based on V2O5 percentage alone.
Size and Form
Published commercial V2O5 flake specifications include fused flake form with maximum thickness of approximately 5 mm and maximum dimensions around 50 × 50 mm to 55 × 55 mm with low fine-material content where specified.
Applications
- Ferrovanadium Production: V2O5 flake is used as the principal vanadium-bearing feedstock in ferrovanadium production.
- Steel Alloying: Converted into ferrovanadium or other vanadium alloys for use in steelmaking applications including constructional steels, tool steels, and automotive components.
- Vanadium-Based Materials: Intermediate for vanadium-containing master alloys and other industrial vanadium materials.
Technical Information
The purchasing relationship can be summarized as: V2O5 grade → impurity profile → ferrovanadium process → final alloy chemistry → steel application. For ferrovanadium producers, the V2O5 assay and impurity profile are important because the feedstock becomes part of the reduction and alloy-forming charge.

Quality and Documentation
Typical purchasing documentation includes Certificate of Analysis, Safety Data Sheet, Packing List, batch or lot information, and inspection report when required. For metallurgical applications, the COA should identify V2O5 and the principal impurity elements required by the buyer's production specification.
Packing
Commercial V2O5 flakes are supplied in industrial packaging such as steel drums and bulk bags. Published references include approximately 200–250 kg drums and 1 MT bulk bags. The final packing configuration should be specified according to the shipment and handling requirements.
