Cd-U system (cadmium-uranium)

The solubility of uranium in the Cd-rich liquid has been well established and is represented by: log (wt % U) = 8.174-6.766 x 103T-1 + .0726 x 106T-2 (320 to 4730C) and log (wt. % U) = 1.754 to 2.593 x 103T-1 + 1.179 x 106T-2 (473 to 6500C). Thermodynamic properties have been determined from emf measurements and vapor pressure data. The emf data lead to Δ G/sub f/0 = 27200 + 36.2T cal/mol for the reaction of U(α) + 11Cd(l) → UCd11(s), which is preferred over the analogous relation obtained from vapor pressure data. The dissociation pressure of UCd11 in the temperature range of 305 to 3680C is given by log P/sub Cd/ (mmHg) = 9.060 - 6105T-1. Phase diagrams are included. 2 figures
