Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V2O5. Commonly known as vanadium pentoxide, it is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent. From the industrial perspective, it is the most important compound of vanadium, being the principal precursor to alloys of vanadium and is a widely used industrial catalyst.
The mineral form of this compound, shcherbinaite, is extremely rare, almost always found among fumaroles. A mineral trihydrate, V2O5·3H2O, is also known under the name of navajoite
Uses in Pottery
An acidic metallic oxide which produces yellow coloration in amounts to 10%. Its color in generally weak, but can be strengthened when fritted with tin and zirconia. Although yellows can be prepared with antimony, vanadium is stable at higher temperatures.
The most vibrant color is obtained in transparent glazes.
Also a strong flux.
Colorant used to produce yellow, greenish yellow, reddish brown. Excess (more than can be dissolved in glaze) can cause irregular surfaces. Slightly soluble. Acts as a flux; reduces surface tension.
