vanadium pentoxide
Noun: 1. An inorganic chemical compound: Vanadium pentoxide is the inorganic compound with the formula V₂O₅. It is the most important compound of vanadium, appearing as a yellow to red crystalline powder. It is primarily used as an industrial catalyst and in the production of other vanadium compounds. 2. A catalyst in chemical processes: It is widely used as a catalyst, most notably in the contact process for the production of sulfuric acid.
- Noun:
- The factory uses vanadium pentoxide to catalyze the oxidation of sulfur dioxide.
- Vanadium pentoxide is a key raw material in manufacturing ferrovanadium, an alloying agent for steel.
- The characteristic orange color of the ceramic glaze comes from vanadium pentoxide.
- Industrial Context: In technical and industrial literature, "vanadium pentoxide" is often referred to simply by its chemical formula, V₂O₅.
- The optimal temperature for the V₂O₅ catalyst in this reactor is 450°C.
- Vanadium (V) (noun): The metallic chemical element (atomic number 23) from which vanadium pentoxide is derived.
- Catalyst (noun): A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Vanadium pentoxide is a specific type of catalyst.
- Oxide (noun): A chemical compound of oxygen with another element. Vanadium pentoxide is an oxide of vanadium.
- Divanadium pentaoxide: The systematic IUPAC name.
- Vanadic anhydride: An older name reflecting its property of forming vanadic acids when combined with water.
- V₂O₅: The standard chemical formula abbreviation.
The provided reference context defines "vanadic acid" (any of various oxyacids of vanadium). It is important to distinguish: * Vanadium pentoxide (V₂O₅) is the anhydride (the water-free oxide). * Vanadic acids are the compounds formed when V₂O₅ dissolves in water or alkaline solutions. Therefore, vanadium pentoxide itself is not an acid, but it is the precursor to vanadic acids.
-
any of various oxyacids of vanadium; known mostly in the form of its salts
