Abstract: Diffusion coeffs. were detd. for 22Na+, 86Rb+, 137Cs+, and 36Cl- ions in molten UCl4 as well as in the binary NaCl-UCl4, RbCl-UCl4, and CsCl-UCl4 mixts. contg. 50 and 75 mol % UCl4. Values of diffusion coeffs. were measured by the capillary method. Values of diffusion activation energy were detd. and compared with values of activation energy of molar conductance. The Nernst-Einstein equation was applied to calcn .of the theor. values of cationic conductance in the investigated melts. Values of obtained conductance are compared with those detd. exptl. Concn. dependence of elec. conductance is presented for MCl-UCl4 systems at comparative temps. Besides, mechanism of charge transfer in the examd. molten solns. is discussed.
