6 FAQs about [Solid containing uranium oxygen fluorine]
Which uranium oxyfluoride must be formed before UF 6 (g)?
Therefore, uranium oxyfluorides (UO 2 F 2 (s) or UOF 2 (s)) must be formed prior to formation of UF 6 (g). Figure 11 shows that UOF 2 (s) is the intermediate oxyfluoride formed during UO 2 (s) fluorination with F 2 (g), since there is possible equilibrium between them.
What is uranium hexafluoride?
Uranium hexafluoride - with the chemical formula UF6 - is a chemical compound that contains one atom of uranium and six atoms of fluorine (see figure 1). In its solid form, uranium hexafluoride is a white crystalline substance (see figure 2). This uranium compound is used during the uranium enrichment process.
How are uranium oxyfluorides formed?
The reaction mechanisms, intermediates and final products were analyzed using different thermodynamic calculations, including free energy change, phase stability and equilibrium composition diagrams. In the U–O–F system uranium oxyfluorides are necessarily formed between uranium oxides and fluorides.
What are the final products of uranium fluorination?
The final products of the fluorinations of UO 2 (s) and UO 3 (s) are UF 4 (s) and UF 6 (s,l,g) in the reactions with HF (g) and F 2 (g), respectively. In the fluorination with F 2 (g), in addition to oxyfluorides formation, intermediate uranium fluorides could be formed before the final UF 6 is obtained.
How to prepare UF 6 from uranium oxides?
Several methods have been reported for preparing UF 6 from uranium oxides with different fluorination agents such as cobaltic fluoride, fluorine at atmospheric and high pressure, liquid bromine trifluoride and nitrogen trifluoride .
Can intermediate uranium fluorides be formed before UF 6?
In the fluorination with F 2 (g), in addition to oxyfluorides formation, intermediate uranium fluorides could be formed before the final UF 6 is obtained. This study aims to clarify thermodynamic information in fluorination treatment of uranium oxides.
