Effects of vanadium compounds on plant photosynthesis.

The effect of vanadium on growth and performance of photosynthetic apparatus of plants is controversial. In general, the toxicity of vanadium compounds is low. Pentavalent compounds are the most toxic and the toxicity of vanadium compounds usually increases as the valence increases. The effect of the treatment with vanadium on growth and photosynthesis for pepper plants is presented in …

Vanadium - Wikipedia

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...

Vanadium - Element information, properties and uses ...

Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium alloys are used in nuclear reactors because of vanadium's low neutron-absorbing properties.

About Vanadium – Bushveld Minerals

Accordingly, the ability to guarantee supply of vanadium for VRFBs will be key to the success of these systems. Stability of vanadium input costs: vanadium makes up between 30 and 50% of the cost of a VRFB system, depending on the battery size and vanadium price. The adoption of VRFBs thus depends on the relative and absolute vanadium price.
