Vanadium(V) oxide

Vanadium(V) oxide (vanadia) is the <a href="/facts/Inorganic_compound/TfFfzxSz">inorganic compound</a> with the <a href="/facts/Chemical_formula/hghUtthl">formula</a> <a href="/facts/Vanadium/UvKkKTSm">V</a>2<a href="/facts/Oxygen/acyn6o8r">O</a>5. Commonly known as vanadium pentoxide, it is a dark yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high <a href="/facts/Oxidation_state/W53W6s6V">oxidation state</a>, it is both an <a href="/facts/Amphoteric/2UrXEsyl">amphoteric</a> oxide and an <a href="/facts/Redox/Pyd5RVcj">oxidizing agent</a>. From the industrial perspective, it is the most important compound of <a href="/facts/Vanadium/UvKkKTSm">vanadium</a>, being the principal precursor to <a href="/facts/Vanadium_alloy/UvKkKTSm">alloys of vanadium</a> and is a widely used <a href="/facts/Industrial_catalyst/9epNn8SE">industrial catalyst</a>.
The mineral form of this compound, shcherbinaite, is extremely rare, almost always found among <a href="/facts/Fumaroles/BX3XEkj5">fumaroles</a>. A mineral <a href="/facts/Hydrate/dev82l69">trihydrate</a>, V2O5·3H2O, is also known under the name of navajoite.
