Absorption, Distribution and Excretion:
In an exptl study in which humans were exposed to Vanadium Trioxide dust, with tests being run before, during, and after exposure, the greatest amount of vanadium was found in urine 3 days after exposure;
none was detectable after a week.
Fecal vanadium was at a max of 0.003 mg/g;
none was detected after 2 weeks
Metabolism/Metabolites:
Within tissues in organisms, V3+ and V4+ predominate because of largely reducing conditions; in plasma, however, which is high in oxygen, V5+ is formed.
Use and Manufacturing:
-Catalyst, e.g., when making ethanol from ethylene.
-The most important application is as an alternative to V2O5 in the production of:
-FeV

Vanadium Trioxide Prepared by reduction of V2O5 with hydrogen or carbon monoxide.
Vanadium Trioxide can be prepared by reduction of the pentoxide or ammonium metavanadate by natural gas, hydrogen or carbon.
Under environmental conditions, Vanadium Trioxide may exist in oxidation states +3, +4, and +5.
V3+ and V4+ act as cations, but V5+, the most common form in the aquatic environment, reacts both as a cation and anionically as an analogue of phosphate.

Vanadium Trioxide (Vanadium Sesquioxide) is one of several oxide forms of vanadium suitable for glass, optic and ceramic applications.
Oxide compounds are not conductive to electricity.
However, certain perovskite structured oxides are electronically conductive finding applicationin the cathode of solid oxide fuel cells and oxygen generation systems.
They are compounds containing at least one oxygen anion and one metallic cation.
They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity.
Metal oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions.
Vanadium Trioxide is generally immediately available in most volumes.
High purity, submicron and nanopowder forms may be considered.
Vanadium Trioxide has an orthorhombic crystalline structure that increases reactivity in chemical applications.
Vanadium Trioxide is the highest purity vanadium trioxide in the world and is used in various alloys as well as chemical applications.
