Description
Vanadium Pentoxide (CAS 1314-62-1), also known as vanadic anhydride, vanadia, or C.I. 77938, is an inorganic compound of vanadium in its highest oxidation state. It serves as a primary catalyst precursor and oxidising agent across industrial chemistry, with no assigned E-code or food-grade classification.
In sulphuric acid production, it catalyses the oxidation of sulphur dioxide to sulphur trioxide via a redox cycle between V(V) and V(IV) states, enabling continuous regeneration without consumption. It is also used in the manufacture of maleic anhydride and as a dopant in electronic ceramics, where it modifies electrical conductivity in varistor and thermistor components.
Vanadium Pentoxide is supplied in technical and catalyst grades, typically as powder or granules. It falls under REACH regulation (EC 1907/2006) and is subject to SVHC screening given its classification as a reproductive toxicant. Packaging is available in multi-layer bags and intermediate bulk containers.
