Q: What is uranium?
A: Uranium is a chemical element in the periodic table that has the symbol U and atomic number 92. Heavy, silvery-white, metallic, naturally radioactive, uranium belongs to the actinide series. Its isotopes 235U and to a lesser degree 233U are used as the fuel for nuclear reactors and the explosive material for nuclear weapons.
Q: What is Depleted Uranium?
A: Depleted Uranium (DU) is uranium remaining after removal of the isotope uranium-235. It is primarily composed of the isotope uranium-238. In the past it was called by the names Q-metal, depletalloy, and D-38, but these have fallen into disuse. Since depleted uranium contains less than one third as much uranium-235 and uranium-234 as natural uranium, it is weakly radioactive and an external radiation dose from depleted uranium is about 60% of that from the same mass of uranium with a natural isotopic ratio. Depleted uranium (238U) is used in kinetic energy penetrators and armor plating.
Q: What is Vanadium
A: Vanadium(V) oxide (vanadia) is the chemical compound with the formula V2O5. Commonly known as vanadium pentoxide, this brown/yellow solid is the most stable and common compound of vanadium. Upon heating it reversibly loses oxygen. Related to this ability, V2O5 catalyses several useful aerobic oxidation reactions, the largest scale of which underpins the production of sulfuric acid from sulfur dioxide. It is a poisonous brown/yellow solid which, because of its high oxidation state, is both an amphoteric oxide and an oxidising agent. Unlike most metal oxides, it dissolves slightly in water to give a pale yellow, acidic solution. When this compound is formed by precipitation from aqueous solution, then its color is deep orange instead of brown/yellow. (Source: www.wikipedia.org)
Q. What is it used for
The major use of vanadium pentoxide is in the production of metal alloys. Iron–vanadium
and aluminium–vanadium master alloys (e.g. for automotive steels, jet engines and
airframes) are produced preferably from vanadium pentoxide fused flakes because of the
low loss on ignition, low sulfur and dust contents, and high density of the molten oxide
compared with powder. (Source: www.wikipedia.org)
