THERMODYNAMIC PROPERTIES OF SOLUTIONS OF CERIUM CHLORIDE IN MOLTEN ALKALI HALIDES

The thermodymamic properties of solutions of CeCl/sub 3/ in KCl and NaCl were determined over a concentration range extending from pure CeCl/sub 3/ to 10/ sup -3/ mole fraction. The effects of NaCl and KCl as diluents are compared. and it is found that the CeCl/sub 3/--NaCl system is more nearly ideal in its behavior than the CeCl/sub 3/-KCl solution. Experimentally determined thermodynamic values for CeCl/sub 3/ between 800 and 900 deg C are given. (W.L.H.)
