PuF4

Plutonium tetrafluoride (PuF₄) is a ceramic compound and an actinide fluoride used primarily in nuclear fuel cycle operations and weapons-grade plutonium processing. This material is encountered almost exclusively in specialized nuclear facilities where it serves as an intermediate compound in plutonium metallurgy and enrichment processes, making it relevant only to nuclear weapons programs, advanced fuel manufacturing, and nuclear security contexts. PuF₄ is notable for its chemical stability and fluorine affinity, which enables separation and purification of plutonium from other actinides, though its extreme toxicity, radiotoxicity, and strict regulatory classification make it unsuitable for any civilian commercial application.
