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.
There are two aspects to the harmful effects of plutonium: radioactivity and heavy metal poisoning. Plutonium compounds are radioactive and accumulate in bone marrow. Contamination by plutonium oxide has resulted from nuclear disasters and radioactive incidents, including military nuclear accidents where nuclear weapons have burned. [139]
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 ]

Plutonium oxide is substantially more toxic than uranium oxide, making fuel manufacture more difficult and expensive. As plutonium isotopes absorb more neutrons than uranium fuels, reactor control systems may need modification. MOX fuel tends to run hotter because of lower thermal conductivity, which may be an issue in some reactor designs.
Plutonium(IV) iodate is an inorganic compound with the chemical formula Pu(IO 3) 4, it is a salt which decomposes into plutonium(IV) oxide above 540 °C. [3] It can be generated in the reaction of plutonium(IV) nitrate and iodic acid, but this method cannot obtain a pure product; [3] Another preparation method is the reaction of plutonium(IV) nitrate or plutonium(IV) chloride with potassium ...
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.
