Experimental investigation and thermodynamic modelling of the ThF4-PuF3 phase diagram
Phase equilibria in the system ThF4-PuF3 were measured by DSC. Samples were encapsulated to prevent leak during the measurements and to protect the internal parts of the device from the corrosive fluoride vapours. Formation of intermediate compounds and solid solutions was investigated by XRD. A thermodynamic model based on CALPHAD approach was developed for the measured system. Good fit between measurements and phase equilibria calculated using the model was achieved.
