Summary: | The handling of spent uranium hexafluoride is extensively explained in the literature, and some developments have been tested on commercial scales. The reduction of depleted uranium hexafluoride by unsaturated halogen derivatives of organic compounds to depleted uranium tetrafluoride and subsequent solid-phase interaction of the tetrafluoride with silica make it possible to obtain together with uranium oxides highly pure silicon tetrafluoride. In a study by means of differential thermal analysis combined with mass-spectrometry of the interaction of depleted uranium tetrafluoride produced in Russia with different crystalline and x-ray amorphous forms of silica, it was established that the rate of heating of a mixture has only a very weak effect on the process: as this rate decreases from 25 to 5C/min, the interval where SiF4 precipitates shifts into the low-temperature region by only 2030C. |
