摘要：

For a better understanding of the mechanism of electrical conductivity of ionic melts, additive binary systems yield more heuristic information than pure melts do. Thus, mobility isotherms of monovalent cations with a common anion are discussed. The difference in external and internal mobilities is explained. The methods for determining transport numbers of individual ionic species in mixtures are briefly mentioned. The profiles of the isotherms of the internal mobilities of monovalent cations in common anion binary systems may be classified into two types. In most of the binary melts a crossing of the isotherms occurs. Interpretation of the ionic mobilities reversal is given based on molecular dynamics simulation as well as experimental data, which is a clue for elucidation of the mechanism of ionic transport in molten salts. © 1990.
