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.
