OSTI ID:5919480
The Knudsen effusion-mass spectrometric technique has been used in this laboratory to study the congruent vaporization and thermal decomposition of several lanthanide and actinide fluorides. Reported here are the results of experiments which were performed to establish the thermal stability of AmF/sub 4/(s) and CeF/sub 4/(s). Cerium tetrafluoride thermally decomposed in the region of 700/sup 0/C. Americium tetrafluoride thermally decomposed in the region of 600/sup 0/C. 11 refs., 1 fig., 1 tab.
