Thermal Analysis Studies of the Decomposition of Ammonium Uranyl Carbonate (AUC) under Simulated Industrial Conditions

  • Lars Hälldahl

In a previous study (1) the decomposition and subsequent reduction of AUC were examined by conventional thermal analysis (TG and DTA) and the nature of the intermediate products formed during these processes in different atmospheres was established. A new series of measurements has been carried out in a modified thermobalance system in which the rapid heating of the AUC powders, characteristic of the industrial process, can be simulated. The equipment constructed for these measurements and the results obtained by this method in an actual industrial atmosphere are discussed in this paper.
