- n. A bright white, soft, ductile metallic element found in several minerals, notably vanadinite and carnotite, having good structural strength and used in rust-resistant high-speed tools, as a carbon stabilizer in some steels, as a titanium-steel bonding agent, and as a catalyst. Atomic number 23; atomic weight 50.942; melting point 1,890°C; boiling point 3,000°C; specific gravity 6.11; valence 2, 3, 4, 5. See Table at element.

- n. A rare element of the nitrogen-phosphorus group, found combined, in vanadates, in certain minerals, and reduced as an infusible, grayish-white metallic powder. It is intermediate between the metals and the non-metals, having both basic and acid properties. Symbol V (or Vd, rarely). Atomic weight 50.94 (C12=12.000).
from The Century Dictionary and Cyclopedia
- n. Metallic vanadium in a compact state has been obtained by fusion in an electric furnace. It has a gray color, is lustrous, and, as thus far observed, brittle, though perhaps this may be due to impurity of the metal; it is with difficulty freed from oxygen, carbon, and nitrogen.
- n. Chemical symbol, V; atomic weight, 51.2. A metal first discovered by Del Rio, in 1801, in a lead ore from Mexico, and called by him erythronium, because its salts became red when heated with acids.

In the journal Science, researchers at the University of California-Irvine say they've manipulated a bacterial enzyme called vanadium nitrogenase that usually produces ammonia from nitrogen gas.
One promising flow battery type is called a vanadium redox battery, and the way it works sheds some light on why these batteries can last so long.
As it happened, in addition to radium, carnotite rock also contained much larger quantities of a metal called vanadium, which proved to be a hardening agent when blended into steel.
Swanwick called vanadium the most boring element, since all he could uncover about it is that it is essential to a chicken's diet.
Henry Ford built a tough, light compact prototype he called the Model T in 1908, helped by a new invention known as vanadium steel that was three time tougher than ordinary steel.
However, it is Vanadium's new use in the renewable energy field that is getting investors' attention, with Discover Magazine calling vanadium " The element that could change the world".
Minerals found in association with uranium, especially vanadium, which is used in hardening steel, sparked the first real rush in the 1930s; uranium for bombs and energy then followed in a stuttering pattern of boom and bust into the 1980s, when the nation's nuclear energy program mostly went into mothballs.
Last week it acquired a portfolio of patents and related applications for higher-end RF silicon-carbide chips using a process called vanadium doping from Daimler AG.
In its release on the transaction, Cree (NASDAQ: CREE) pointed in particular to one US patient relating to a process called vanadium-doping, which is adding that alloy to a silicon carbide crystal wafer to produce enhanced photo-electric effects.
Finally, there's the prospect for what's known as vanadium reduction-oxidation batteries, also known as redox batteries.
