  2. Plutonium compounds - Wikipedia

    en.wikipedia.org/wiki/Plutonium_compounds

    Various oxidation states of plutonium in solution. Plutonium compounds are compounds containing the element plutonium (Pu). At room temperature, pure plutonium is silvery in color but gains a tarnish when oxidized. [1] The element displays four common ionic oxidation states in aqueous solution and one rare one: [2] Pu(III), as Pu 3+ (blue lavender)

    en.wikipedia.org/wiki/Plutonium

    Plutonium–gallium–cobalt alloy (PuCoGa 5) is an unconventional superconductor, showing superconductivity below 18.5 K, an order of magnitude higher than the highest between heavy fermion systems, and has large critical current. [46] [50] Plutonium–zirconium alloy can be used as nuclear fuel. [51]

  4. Actinide chemistry - Wikipedia

    en.wikipedia.org/wiki/Actinide_chemistry

    Plutonium is a transuranic radioactive chemical element, an actinide metal. Actinide chemistry (or actinoid chemistry) is one of the main branches of nuclear chemistry that investigates the processes and molecular systems of the actinides. The actinides derive their name from the group 3 element actinium.

    en.wikipedia.org/wiki/Allotropes_of_plutonium

    Plutonium in the delta (δ) phase [7] normally exists in the 310 °C to 452 °C range but is stable at room temperature when alloyed with a small percentage of gallium, aluminium, or cerium, enhancing workability and allowing it to be welded in weapons applications. The δ phase has more typical metallic character and is roughly as strong and ...

  7. Plutonium nitride - Wikipedia

    en.wikipedia.org/wiki/Plutonium_nitride

    Plutonium nitride can be prepared by the reaction of plutonium hydrides with nitrogen or ammonia at a temperature of 650 °C and a pressure of 0.3 kPa. [3] Another method to prepare plutonium nitride is from the reduction of plutonium(III) iodide with sodium in liquid ammonia: PuI 3 + NH 3 + 3Na → PuN + 3NaI

  8. Isotopes of plutonium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_plutonium

    Plutonium-240 has a high rate of spontaneous fission, raising the background neutron radiation of plutonium. Plutonium is graded by proportion of 240 Pu: weapons grade (<7%), fuel grade (7–19%) and reactor grade (>19%). Lower grades are less suited for bombs and thermal reactors but can fuel fast reactors.
