Plutonium(III) fluorideorplutonium trifluoride is the chemical compound composed of plutonium and fluorine with the formula PuF3. This salt forms violet crystals. Plutonium(III) fluoride has the LaF3 structure where the coordination around the plutonium atoms is complex and usually described as tri-capped trigonal prismatic.[3]
A plutonium(III) fluoride precipitation method has been investigated as an alternative to the typical plutonium peroxide method of recovering plutonium from solution, such as that from a nuclear reprocessing plant.[4] A 1957 study by the Los Alamos National Laboratory reported a less effective recovery than the traditional method,[5] while a more recent study sponsored by the United States Office of Scientific and Technical Information found it to be one of the more effective methods.[6]
Plutonium(III) fluoride can be used for manufacture of the plutonium-gallium alloy instead of more difficult to handle metallic plutonium.
