High-purity vanadium pentoxide (V₂O₅)

Description

1. Product Overview
High-purity vanadium pentoxide (V₂O₅) is a critical transition metal oxide serving as the primary feedstock for vanadium alloys, specialty chemicals, and advanced energy storage systems. Its primary industrial use lies in high-strength steel production (as ferrovanadium) and vanadium redox flow batteries (VRFBs) for grid-scale energy storage. The key value proposition is exceptional purity and consistent particle morphology, which directly enhances final alloy performance and electrochemical efficiency. As global decarbonization accelerates demand for vanadium in green steel and long-duration batteries, this product is strategically positioned at the intersection of industrial resilience and the energy transition.

2. Key Specifications & Technical Characteristics

• Chemical composition: Vanadium pentoxide (V₂O₅), ≥99.5% purity

• Impurity limits (max): Fe 0.10%, Si 0.08%, P 0.02%, S 0.01%, As 0.01%, K+Na 0.15%

3. Core Industrial Applications

• Primary industries: Steel manufacturing (specialty alloys), energy storage (VRFBs), chemical catalysts (sulfuric acid production), and titanium-aluminum-vanadium aerospace alloys.

• Specific operational use cases:

  • High-strength low-alloy (HSLA) steel: Added as ferrovanadium (0.05–0.15% V) to boost tensile strength without weight gain.

  • Vanadium redox flow batteries: Dissolved in electrolyte solutions; high purity prevents membrane fouling and capacity decay.

  • Sulfuric acid catalysts: Used as V₂O₅-based active phase for SO₂ to SO₃ conversion.

• Performance advantage: Our consistent particle size distribution reduces melting losses in alloying by 12–15% versus variable-grade material. For VRFBs, lower trace metals (especially Fe, Cr) extend electrolyte life by up to 30%, lowering levelized cost of storage.
