Vanadium pentoxide is the most common commercial form of vanadium. It is used as a catalyst in the production of sulfuric acid and some nanomaterials. When fuel oils containing vanadium are combusted, they leave behind byproducts containing vanadium pentoxide in the forms of dust, soot, boiler scale, and fly ash. Vanadium is found at multiple Superfund sites.
