Vanadium (iii) oxide

Vanadium (III) Oxide (CAS 1314-34-7, EC 215-230-9, formula O3V2) is an inorganic vanadium compound also referred to as vanadic oxide, vanadium oxide, and listed under C.I. 77938. It carries no assigned E-code and is classified within the Salts & Minerals category. It is distinct from the pentavalent form despite sharing some common names in trade contexts.

In catalytic applications, Vanadium (III) Oxide serves as a precursor or active component in redox catalyst systems, where its ability to cycle between oxidation states drives selective oxidation reactions in chemical manufacturing. It is also used in the electronics sector as a functional material in thermistor and switching device production, where its metal-insulator transition properties are exploited. The mining and metals industry applies it in vanadium recovery and refining processes.

This material is supplied as a black powder and is subject to REACH registration requirements for quantities above one tonne per year within the EU. Procurement teams should confirm supplier SDS documentation and purity grade specifications prior to ordering. HS code 28253090 applies for customs classification across EU member states.
