Description

Vanadylsulphate is a vital inorganic compound primarily recognized as a key source of vanadium, a transition metal with significant catalytic and electrochemical properties. This product is essential for industries requiring precise vanadium doping or the introduction of vanadyl (VO²⁺) ions into various matrices. It is particularly sought after by manufacturers in the catalyst production, energy storage, and specialty chemical synthesis sectors for its role in creating high-performance materials and facilitating specific oxidation reactions.

Application

• Catalyst Manufacturing: Serves as a precursor for vanadium-based catalysts used in sulfuric acid production and selective oxidation processes.
• Electrolyte for Flow Batteries: A critical active material in vanadium redox flow batteries (VRFBs) for large-scale energy storage solutions.
• Ceramic & Glass Pigments: Used to impart yellow to green colors in ceramics, glasses, and enamels.
• Nutritional Supplements & Animal Feed: Employed as a source of vanadium, a trace mineral, in specific nutritional formulations (subject to appropriate grade and regulatory compliance).
• Chemical Synthesis: Acts as a versatile reagent and intermediate in organic synthesis and the preparation of other vanadium compounds.
• Corrosion Inhibition: Utilized in certain formulations to provide corrosion protection on metal surfaces.
• Laboratory & Research: Used as a standard or reagent in analytical chemistry and materials science research.
