- The kinetics of uranium dioxide fluorination were studied using an experimental system in which a molecular beam of fluorine was directed at a heated uranium dioxide single crystal wafer maintained in high vacuum. Gaseous reaction products desorbed from the uranium dioxide were monitored by a quadrupole mass spectrometer with an off-axis electron multiplier. The fluorine beam was modulated; ac phase-lock detection and pulse counting were employed to enhance the signal-to-noise ratio. The uranium dioxide targets were heated from the rear by electron bombardment to a maximum of 1800/sup 0/K. Fluorination of the uranium dioxide was found to produce uranium tetrafluoride in the 900/sup 0/ to 1600/sup 0/K temperature range, confirming the results obtained from thermodynamic considerations (quasi-equilibrium analysis). Fluorination of the uranium dioxide was found to be affected by some process acting as a flywheel smoothing the phase response of the interaction as the modulation frequency was varied.
