2. Vanadium - Wikipedia

   en.wikipedia.org/wiki/Vanadium

   Physical properties; Phase at ... Vanadium is a chemical element; it has symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.

3. Group 5 element - Wikipedia

   en.wikipedia.org/wiki/Group_5_element

   Vanadium forms oxides in the +2, +3, +4 and +5 oxidation states, forming vanadium(II) oxide (VO), vanadium(III) oxide (V 2 O 3), vanadium(IV) oxide (VO 2) and vanadium(V) oxide (V 2 O 5). Vanadium(V) oxide or vanadium pentoxide is the most common, being precursor to most alloys and compounds of vanadium, and is also a widely used industrial ...

6. Refractory metals - Wikipedia

   en.wikipedia.org/wiki/Refractory_metals

   The physical properties of the refractory elements vary significantly because they are members of different groups of the periodic table. [ 6 ] [ 7 ] The hardness, high melting and boiling points, and high enthalpies of atomization of these metals arise from the partial occupation of the outer d subshell , allowing the d electrons to ...

7. Vanadium carbide - Wikipedia

   en.wikipedia.org/wiki/Vanadium_carbide

   Vanadium carbide is the inorganic compound with the formula V C. It is an extremely hard and refractory ceramic material. With a hardness of 9-9.5 Mohs, it is possibly the hardest metal-carbide known. [2] It is of interest because it is prevalent in vanadium metal and alloys. [3]

8. Vanadium(V) oxide - Wikipedia

   en.wikipedia.org/wiki/Vanadium(V)_oxide

   Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V 2 O 5. Commonly known as vanadium pentoxide, it is a dark yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange.

9. Vanadium compounds - Wikipedia

   en.wikipedia.org/wiki/Vanadium_compounds

   Vanadium pentoxide is a commercially important catalyst for the production of sulfuric acid, a reaction that exploits the ability of vanadium oxides to undergo redox reactions. [2] The vanadium redox battery utilizes all four oxidation states: one electrode uses the +5/+4 couple and the other uses the +3/+2 couple. Conversion of these oxidation ...
