1. Introduction
Vanadium pentoxide is the most common oxide of vanadium, appearing as an orange-yellow crystalline powder or flaky solid. It exhibits amphoteric oxide characteristics, is slightly soluble in water, and readily soluble in acids and alkalis. Its layered crystal structure and variable valence state make it irreplaceable in catalysis, electrochemical energy storage, and optical materials. With the development of global new energy, fine chemicals, and high-end manufacturing industries, the demand for high-purity, low-impurity vanadium pentoxide continues to grow. As the world’s largest vanadium producer, China, leveraging its resource advantages and technological advancements, has become a core link in the global vanadium pentoxide supply chain.

2. Product characteristics and specifications
The main technical indicators of vanadium pentoxide include purity, impurity content, particle size distribution, and physical morphology. Customer requirements vary depending on the application.
- Purity grades: Industrial grade (98% ~ 99.5%), high-purity grade (99.9% ~ 99.99%). High-purity products are mainly used in electronic, optical, and specialty catalysts.
- Impurity control: Typical limits include elements such as sodium, potassium, iron, silicon, and sulfur being kept below a certain threshold to ensure the stable performance of downstream products.
- Physical form: powder (easy to disperse and mix) or flakes (easy to transport and feed), particle size can be customized (e.g., D50 = 10~50 μm).
- Typical specification example:
- V₂O₅ content ≥ 99.5%
- Impurities Fe ≤ 0.05%, S ≤ 0.03%, Na ≤ 0.02%
- Sheet size: 5~15 mm or as per customer requirements
3. Main application areas
3.1 Catalyst Industry
Vanadium pentoxide is the most important catalyst (vanadium catalyst) in sulfuric acid production, used to oxidize sulfur dioxide to sulfur trioxide. Furthermore, it is widely used in organic synthesis:
- Ethanol oxidation to acetaldehyde
- Oxidation of o-xylene to produce phthalic anhydride
- Preparation of intermediates such as polyamide and oxalic acid
- Active components in flue gas denitrification (SCR denitrification catalyst)
3.2 Glass and Optical Materials
Vanadium pentoxide can be used as a colorant or ultraviolet absorber for glass, in the production of special optical glasses, filters, and photochromic materials. Its high melting point and thermal stability also make it suitable for use in ceramic glazes and electronic ceramics.
3.3 Energy Materials
- Vanadium batteries: Vanadium pentoxide is a key raw material for all-vanadium redox flow batteries, used to prepare electrolytes and achieve large-scale energy storage.
- Cathode material: In lithium-ion batteries, vanadium oxide can be used as a component of high-capacity cathode materials.
- Ferrites and magnetic materials: used to manufacture soft magnetic ferrites and microwave devices.
3.4 Metallurgy and Alloys
Vanadium pentoxide is the main raw material for producing ferrovanadium (FeV). As an alloying additive, ferrovanadium can significantly improve the strength, toughness and wear resistance of steel, and is widely used in construction, bridges, pipelines and tool steel.
3.5 Pigments and others
- Inorganic pigments: used in ceramic glazes, glass coloring, and high-temperature resistant coatings.
- Fluorescent materials: used as phosphor matrix or activator.
4. The core advantages of Chinese manufacturing
China possesses the world’s most complete vanadium industry chain, encompassing the mining and extraction of vanadium-titanium magnetite, as well as its refined processing, resulting in economies of scale and cost advantages. Specifically, this is reflected in:
- Resource advantages: China has one of the world’s largest vanadium reserves, with the Panxi region and Chengde being the main vanadium producing areas.
- Mature technology: Advanced purification technologies such as precipitation, pyrolysis, and solvent extraction are used to stably produce high-purity products.
- Environmental compliance: In recent years, the industry has upgraded its environmental protection practices, significantly improving its clean production level and meeting international environmental standards.
- Flexible supply chain: It can quickly respond to small-batch, multi-specification customization needs, with short delivery time and a well-developed logistics network.
