The U–F System
Résumé
Although UF6 and UF4 have been well characterized and used over the years, some work remains to be done on intermediate fluorides (enthalpy of formation and heat capacity) and the phase diagram (peritectic and eutectic temperatures with composition of the liquid and liquidus temperatures). In particular, the mechanisms leading to the formation of these undesirable compounds in industrial reactors are not very well known. This knowledge would help in improving yields during UF6 preparation process.
