Vanadium Pentoxide Flake 99% min – V₂O₅99 / 98 / 97
Vanadium pentoxide flake is the refined vanadium raw material - the feedstock for ferrovanadium and vanadium nitride production and a reagent across chemical and catalytic applications. ZhenAn supplies flake in three refined grades, V₂O₅99, V₂O₅98 and V₂O₅97, each with a certificate of analysis.
What Is Vanadium Pentoxide Flake?
V₂O₅ flake is produced by roasting vanadium-bearing materials, leaching, precipitating and fusing ammonium polyvanadate into dense flake. Flake (fused and crushed) resists dusting and flows well in handling - the reason alloy plants prefer it over powder. It is the direct feedstock for Ferrovanadium FeV80 and the whole FeV family.
What Is the Chemical Composition of V₂O₅ Flake Grades?
Typical values; verify each lot against its COA.
| Grade | V₂O₅ % ≥ | Si % < | Fe % < | P % < | S % < | As % < | Na₂O+K₂O % < |
|---|---|---|---|---|---|---|---|
| V₂O₅99 | 99.0 | 0.15 | 0.20 | 0.05 | 0.01 | 0.01 | 1.0 |
| V₂O₅98 | 98.0 | 0.25 | 0.30 | 0.05 | 0.03 | 0.02 | 1.5 |
| V₂O₅97 | 97.0 | 0.25 | 0.30 | 0.05 | 0.01 | 0.02 | 1.0 |
Packing: 250 kg steel drum (typical; confirm per order).
V₂O₅99 vs 98 vs 97: Which Flake Grade Does Your Process Need?
The three refined grades share the same flake form - what differs is purity and the residuals that follow it downstream.
| Property | V₂O₅99 | V₂O₅98 | V₂O₅97 |
|---|---|---|---|
| V₂O₅ content | ≥99.0% | ≥98.0% | ≥97.0% |
| Iron | <0.20% | <0.30% | <0.30% |
| Sulfur | <0.01% | <0.03% | <0.01% |
| Best for | Residual-sensitive applications | Common ferrovanadium feedstock | General alloy charge |
Confirm the grade against your process specification - our sales team can match it to your furnace practice.
Where Is Vanadium Pentoxide Flake Used?
- Feedstock for ferrovanadium (FeV40–FeV80) and vanadium nitrogen alloy (VN12/VN16) production
- Vanadium chemicals and catalysts
- Glass and ceramics coloring
- Battery-material research feedstock
How Is V₂O₅ Flake Quality Verified?
Each lot is analyzed for V₂O₅ content and residual impurities with results on the COA; third-party inspection available.
Why Source Vanadium Pentoxide Flake from ZhenAn?
Manufacturer-direct refined V₂O₅ in all three grades, drum packing verified at weighing, and paired supply of the ferrovanadium it feeds - one supplier from raw material to finished alloy.
What Do V₂O₅ Flake Buyers Ask Most?
Which V₂O₅ grade do I need for ferroalloy production?
V₂O₅98 is common for ferrovanadium feedstock; V₂O₅99 for applications sensitive to metallic residuals. Confirm against your process specification.
Flake or fused flake?
Both are fused material; flake grades here are the standard alloy-plant feedstock. See our vanadium pentoxide fused flake page for the large-format 20–80 mm product.
How is V₂O₅ flake packed?
250 kg steel drums, palletized for container loading (confirm per order).
What is V₂O₅ flake used for besides ferroalloys?
Vanadium chemicals, catalysts, glass and ceramics coloring, and battery-material research feedstock.
How is quality verified?
The COA of each lot reports V₂O₅ content and residual impurities; third-party inspection can be arranged.
Is flake dusty to handle?
Fused flake dusts far less than powder - one of the main reasons alloy plants specify flake.
