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.
It also reacts readily with oxygen, forming PuO and PuO 2 as well as intermediate oxides; plutonium oxide fills 40% more volume than plutonium metal. The metal reacts with the halogens, giving rise to compounds with the general formula PuX 3 where X can be F, Cl, Br or I and PuF 4 is also seen. The following oxyhalides are observed: PuOCl ...
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] The tetrahydrate has been used as a primary analytical standard for plutonium. [5]

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 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.
