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.
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 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) 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.

Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 is also used for that purpose. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233. Plutonium-239 has a half-life of 24,110 years. [1]
The thorium(IV) hydrated ion is quite acidic due to its high charge, slightly stronger than sulfurous acid: thus it tends to undergo hydrolysis and polymerisation, predominantly to [Th 2 (OH) 2] 6+ in solutions with pH 3 or below, but in more alkaline solution polymerisation continues until the gelatinous hydroxide is formed and precipitates ...
