摘要
Concentrated solution theory is generalized to provide a framework for the description of isothermal transport processes in a mixture of two binary molten salts with a common ion. Electrochemical flux equations are derived for several, commonly used reference velocities. Nonsteady-state material balances and conservation equations, based on the macrohomogeneous theory of porous electrodes, are also presented, together with a relationship for the ohmic potential drop in the solution. These equations, can be used in conjunction with information on electrode kinetics to predict the behavior of molten salt electrolytes in porous media or in free electrolytic solutions. © 1979, The Electrochemical Society, Inc.
