Plutonium(III) phosphate is an inorganic compound of plutonium, with the molecular formula . It is the trivalent plutonium salt of phosphoric acid.
Preparation Heating a mixture of plutonium dioxide and diammonium phosphate to 1000°C for 12 hours produces polycrystalline plutonium phosphate.
Heating the product to 1100°C produces plutonium dioxide and phosphorus pentoxide.
Reacting plutonium(IV) nitrate with disodium phosphate produces which is decomposed to plutonium phosphate when heated to 600°C for 6 hours in an argon/hydrogen atmosphere.
Reacting plutonium(III) fluoride with boron phosphate also produces plutonium phosphate.
Properties Plutonium phosphate crystalizes in the monazite crystal structure.
It does not dissolve in water.
