The thermalstabilities of several lanthanide/actinide tetrafluorides have been studied using mass spectrometry to monitor the gaseous decomposition products, and powder X-ray diffraction (XRD) to identify solid products. The tetrafluorides, TbF/sub 4/, CmF/sub 4/, and AmF/sub 4/, have been found to thermally decompose to their respective solid trifluorides with accompanying release of fluorine, while

Curium metal has been found to crystallize in a double hexagonal close packed structure, similar to that of alpha lanthanum. The lattice parameters are: The meltingpoint of the metal was observed to be 1340 ± 40°C.
