Plutonium(IV) oxide, or plutonia, is a chemical compound with the formula Pu O 2. This high melting-point solid is a principal compound of plutonium . It can vary in color from yellow to olive green, depending on the particle size, temperature and method of production.
238 Pu has become the most widely used fuel for RTGs, in the form of plutonium(IV) oxide (PuO 2). [37] However, plutonium(IV) oxide containing a natural abundance of oxygen emits neutrons at the rate of roughly 2.3 × 10 3 n/sec/g of plutonium-238. This emission rate is relatively high compared to the neutron emission rate of plutonium-238 metal.
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) Pu(IV), as Pu 4+ (yellow brown) Pu(V), as PuO +

Plutonium(IV) sulfate is a chemical compound consisting of plutonium and sulfate ions, with the chemical formula Pu(SO 4) 2 ·xH 2 O. It has been observed as a tetrahydrate , where x =4, [ 1 ] [ 3 ] as well as an anhydrous form, where x =0. [ 2 ]
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
The usual transport of plutonium is through the more stable plutonium oxide in a sealed package. A typical transport consists of one truck carrying one protected shipping container, holding a number of packages with a total weight varying from 80 to 200 kg of plutonium oxide.
Metallic plutonium, notably in the form of the plutonium-gallium alloy, degrades chiefly by two mechanisms: corrosion, and self-irradiation. In very dry air, plutonium, despite its high chemical reactivity, forms a passivation layer of plutonium(IV) oxide that slows down the corrosion to about 200 nanometers per year. In moist air, however ...
