Behaviour of uranium is studied in LiCl–KCl–CsCl eutectic melt over 500° range.
Uranium electrode potentials in LiCl–KCl–CsCl melt are determined at 573–1073 K.
U(III)/(IV) red-ox potentials in LiCl–KCl–CsCl melt are determined at 573–1073 K.
Uranium(III) and (IV) diffusion coefficients are determined at 573–1073 K.
