抄録

The ε values in the internal cation mobilities of (Li, Na, K)(CO₃)_0.5 of the eutectic composition (43.5-31.5-25.0 mol %) in the temperature range from 773 K to 1023 K have been measured by a countercurrent electromigration method, that is the Klemm method, where ε is defined as (u_i − u_j)/u_a; u_a is the average internal cation mobility and subscripts i and j refer to any two of three cations. From the present data and the densities and electric conductivities, the internal cation mobilities of u_Li, u_Na and u_K have been calculated. The internal mobility of Li⁺, u_Li, was compared to the empirical equation expressed for binary alkali carbonates. The orders of the internal cation mobilities were u_K < u_Li < u_Na at 773-873 K, u_Li < u_K < u_Na at 923 K, and u_Li < u_Na < u_K above 973 K, although these were broadly equal to one another. These orders could be interpreted in terms of the dynamic dissociation model previously presented.
