Characteristics of Vanadium
Vanadium is a white, shiny, ductile, malleable metal, and can be elongated and worked into sheets (sheets).
It is resistant to corrosion.
Vanadium is moderately reactive.
They do not react with oxygen in the air at room temperature nor do they dissolve in water.
Does not react with certain acids, such as cold sulfuric or hydrochloric acid.
But it becomes more reactive with hot acids, such as hot sulfuric and nitric.
Vanadium is special in that it acts as a metal (in some cases), and as a non-metal in other cases.
It is a good conductor of heat and electricity.
You can melt it.
It is used to produce corrosion-resistant steels and high-speed steels.
Used as a joining element (in permanent joints by hot rolling) with titanium or steel. It is also used in superconductors.
Vanadium pentoxide (V2O5) is used in ceramics and as a catalyst.
