Vanadium pentoxide

Vanadium pentoxide (CAS 1314-62-1), also referenced commercially as V2O5, is the primary industrial form of vanadium used as a catalyst and catalyst precursor. It drives large-scale oxidation reactions across chemical manufacturing.

This material is particularly vital in sulfuric acid production where it functions as the active catalytic component. In sulfuric acid plants, it catalyzes the oxidation of sulfur dioxide to sulfur trioxide in the contact process.

This specific role makes it indispensable to fertilizer, mining, and chemical manufacturing supply chains. The electronics and energy storage sectors use it as a precursor for vanadium redox flow batteries.

Consistent purity directly affects electrolyte performance in these advanced energy systems. Metallurgical processors use V2O5 as a feedstock for producing ferrovanadium and other vanadium alloys used in high-strength steel.

It also serves as a catalyst precursor in the production of phthalic anhydride from naphthalene or o-xylene oxidation. Vanadium pentoxide is supplied as an orange-yellow powder or fused flake form.

Flakes are common in catalyst manufacturing applications. Technical and metallurgical grades are the most widely traded, with purity levels typically ranging from 98% to 99.5%+ for high-purity catalyst and battery-grade specifications.

Packaging is available in drums and bulk quantities suited to industrial procurement volumes. This ensures reliable supply for large-scale industrial operations and specialized chemical processing facilities worldwide.
