V2O5 Flake Vanadium Pentoxide Yellow Color for Chemical Industry
Flake Vanadium Pentoxide (V₂O₅), Yellow is a high-purity, crystalline form of vanadium pentoxide known for its distinctive bright yellow to orange color, flake-like morphology, and excellent chemical stability. It is widely used in the chemical industry as a key catalyst, oxidizing agent, and precursor in various chemical reactions and industrial processes.
Product Identification
- Chemical Name: Vanadium Pentoxide
- Chemical Formula: V₂O₅
- Molecular Weight: 181.88 g/mol
- CAS Number: 1314-62-1
- Appearance: Bright yellow to orange flaky solid
- Color: Yellow (due to the V⁵⁺ oxidation state)
- Odor: Odorless
- Melting Point: ~690°C
- Boiling Point: Decomposes before boiling (~1750°C)
- Solubility: Slightly soluble in water, soluble in alkalis and concentrated acids
Production & Morphology
Flake V₂O₅ is typically produced through:
- Fusion of vanadium-bearing ores or intermediates (like vanadium slag or V₂O₃) in high-temperature furnaces
- Controlled cooling and crystallization, resulting in flake-like or platelet-shaped crystals
- Post-treatment (optional) such as grinding or classification to adjust particle size while maintaining flake characteristics
Why Flake Morphology?
- Better handling & flowability
- Improved dispersion in slurries
- Easier filtration and separation
- Enhanced surface exposure in catalytic applications
Color Significance
The yellow color of V₂O₅ is characteristic of the pentavalent (+5) oxidation state of vanadium, which is the most stable and common oxidative state for industrial use. This vibrant yellow is often an indicator of high purity and proper crystalline structure.
